    ABSTRACT: Switched mode power converters are the most important circuits for battery powered applications such as hybrid electric vehicles, lighting systems as well as integrated circuits. These converters are usually studied in its ideal form. However, practical converters behave differently due to associated parasites and thus affect both steady state and stability. So, this paper analyses steady state and state space modelling of non-ideal boost converter. A converter is operated in both CCM and DCM modes. Models are derived by considering capacitance effects of diode and switch in addition to other parasites. The models derived are detailed and care has been taken to avoid assumptions and approximations though the models are very complex. The methodology adopted can be easily extended for other converters. Effect of every parasite and switching frequency on performance of the converter are clearly evaluated by plotting time domain and frequency domain plots in MATLAB. Simulation results show that there is a considerable deviation in performance of practical converters from its ideal case and the deviation is just not due to the inclusion of parasites but also due to the shift in operating point (duty cycle).

    ABSTRACT: The paper evolves a three-phase structure for a multilevel inverter (MLI) to extract a variable voltage for the operation of a three-phase induction motor. The series parallel switched nature of the configuration favours to reach the desired level of the output voltage with reduced switch count. The focus corners to exploit the effective regions of the reference wave and travel to accrue the benefits of a different pulse width modulation (PWM) strategy to improve the output voltage harmonic spectrum and minimise its total harmonic distortion (THD). It facilitates the choice of a desired target voltage and there from the preferred speed for the motor in tune with the requirements of different applications. The MATLAB based simulation response reveals the merits of the topology and up heaves the intricacies in the modulation mechanism to claim its suitability. The experimental results obtained from a prototype validate the formulation and forges to create fresh areas of use for MLI driven induction motor drives.

    ABSTRACT: This paper discusses a hybrid multi-level inverter based shunt active filter intended to eradicate the current harmonics on the load side. The proposed shunt active filter utilises instantaneous p-q theory for reference signal generation and triangular periodic controller for switching pulse generation. The main objective is to mitigate the current harmonics under nonlinear balanced and unbalanced load condition. The simulation studies are carried out using MATLAB/Simulink to validate the dynamic behaviour of shunt active filter during voltage and current perturbations.

    ABSTRACT: This paper presents stability analysis and reliability evaluation of three-phase Z-source inverter including load parameters. The impedance network of ZSI is operated for the shoot through period in order to achieve a desired voltage boost at DC link. Therefore, incremental change at DC link voltage of ZSI is a function of incremental change in shoot through ratio. However, impedance network parameters limit the safe range of shoot through ratio. So a novel method has been proposed for selection of inductor and capacitor values of impedance network based on the stability analysis. This method has been used for calculation of impedance network parameters and a ZSI has been designed using these values. The designed inverter is tested on AC drives to control the speed of three phase induction motor of power rating 1 HP. After testing, it has been observed that the reliability measured in terms of mean time between failures (MTBF) achieves 99.62%.

    ABSTRACT: PID controllers have been widely used to control many systems. Despite the simplicity and wide usage of these controllers, determination of the controller parameters is a major problem in the control field. These parameters have a great influence on the controller's performance. This paper presents an alternative way of parameter determination for PID controllers to control static power converters. The particle swarm optimisation (PSO) algorithm was used to obtain optimal proportionalintegral derivative (PID) controller parameters for voltage regulation of a DC-DC Buck converter. Firstly, the mathematical model of the converter was obtained and the controller parameter was optimised via different types of PSO algorithms, and the algorithm which produced the best performance, is selected as the optimisation algorithm. Secondly, the performance of the optimised controller was compared with the classical method, and finally the performance of the optimised (tuned) controller under line and load variations was evaluated by hardware implementation. The controller design, the optimisation procedure, and the controller performance analysis approaches are presented in detail.

    ABSTRACT: This paper presents a novel, nonlinear control scheme for the dutyratio input of the boost converter fed dc motor. The control technique is proposed, extensively analysed and experimentally tested. The proposed design though nonlinear, results in a very simple scheme, ensures that the duty-ratio takes values exclusively in the permitted range, achieves precise speed regulation even in cases of high unknown load disturbances, and does not depend on system parameters and states. Concurrently, the design is formulated in a manner that provides a closed-loop passive system which, as proven in the paper, satisfies all these assumptions and properties that make possible the application of a new advanced nonlinear method which strongly connects passivity with stability. Thus, it is concluded that the boundedness of all closedloop states and system stability are converge to the desired steady-state equilibrium. Theoretical analysis of the proposed technique is verified and confirmed through simulation and experimental results.

    ABSTRACT: This paper deals with a solar photo voltaic (PV) array fed water pumping system. This system includes solar PV array, a boost converter controlled by using perturb and observe (P and O) control algorithm for extracting the maximum power from solar array and the vector control for the controlling speed of an induction motor drive used for driving the water pump. The reference speed is estimated from the affinity law and dc-link voltage proportional-integral (PI) controller. The developed model of the system in Matlab/Simulink has been used to simulate its performance. Simulated results have demonstrated the satisfactory performance of the controllers both in steady state and dynamic conditions.

    ABSTRACT: The paper discusses the problem of speed and rotor position estimation for the Permanent Magnet Synchronous Motor (PMSM) and presents a family of estimation methods. Estimation is done sequentially: first, the EMFs are obtained using a sliding mode observer; then, the speed is estimated. The estimators are based on the model of the PMSM in the stationary reference frame. The paper presents an SM observer for the EMFs (the front observer) and various observers for the speed (the back observers). It is shown that the speed estimation process offers many mathematical options - it can be adaptive, sliding-mode based, algebraic, or it can use a doublemanifold sliding mode structure. The properties of the various speed observers and their feasibility and accuracy are discussed. The method can be applied in a sensorless PMSM drive where the speed and rotor position angle are needed for control implementation. The paper presents the design of the observers along with simulation results and experimental tests.

    ABSTRACT: This paper presents a single-stage isolated power factor corrected power supply (SSIPP) fed permanent magnet brushless DC (BLDC) motor drive. An advantage of fast voltage regulation with single voltage control loop of SSIPP is utilised to develop a power factor correction (PFC) based BLDC motor drive. The speed of BLDC motor is controlled by varying the DC link voltage of the voltage source inverter (VSI) feeding BLDC motor using a single voltage sensor. A boost-flyback SSIPP operating in discontinuous inductor current mode (DICM) is used for the voltage control with improved power quality at AC mains. A fundamental frequency switching of VSI is used instead of pulse width modulation (PWM) switching to avoid high frequency switching losses in it. The performance of the proposed BLDC motor drive is evaluated for wide range of speed control with power quality indices with-in the recommended limits of international power quality standards such as IEC 61000-3-2.

    ABSTRACT: Shunt Active Power Filter (SAPF) can be applied to compensate for existing source-type current harmonics. However, high-precision compensation is difficult because harmonic current has a large variation and the current loop has a steady-state error. A design method for a new practical LCL filter based on SAPF is proposed in this paper. A harmonic model of the LCL filter is built based on SAPF application. The changing relationship between the parameters of the filter and harmonic frequency is then examined. The suitable values for the parameters are determined based on the precondition of having a split ratio of 1, the limit scope of LCL resonance frequency and the ratio of the capacitance branch's impedance parameter in combination with the relationship curve of the inductance parameter ratio and harmonic frequency as well as the respective requirements of the LCL regarding the attenuating properties of lowand high-frequency bands. Finally, the validity and feasibility of the design method are verified by conducting an experiment with SAPF's industrial prototype.

    ABSTRACT: This paper presents a non-linear inductance profile estimation of a Switched Reluctance Machine (SRM) using real-time applicable modelling techniques. The estimation techniques are based on regression analysis and Adaptive Neuro-Fuzzy Inference System (ANFIS). Mathematical models of phase inductance L(I,è) using both the techniques have been successfully tested for various values of phase currents (Iph) and rotor positions (è) of a non-linear SRM. It is observed that the proposed techniques are highly suitable for inductance L(I,è) modelling of SRM, which is found to be in good agreement with the training data used for modelling.

    ABSTRACT: The paper discusses the problem of speed and flux estimation for the induction motor (IM) drive and presents a series of Sliding Mode Observers (SMOs) that are constructed using compound manifolds. Observers with compound manifolds have not been widely investigated because they cannot be designed following a standard procedure; however, it is shown that they have unique and useful properties. The paper introduces the candidate manifolds associated with IM estimation and shows various approaches for designing SMOs with compound manifolds. Generally, using the IM model, it is typical to design observers with simple manifolds. However, since the state transition matrix of the IM model depends on the motor speed, the problem is more complicated - the speed must either be known or it must be estimated. In the paper, several sensored and sensorless observer designs are presented. The paper presents the theoretical developments and shows simulations and experimental results.

    ABSTRACT: In the present scenario, the development of multilevel inverter is becoming popular for industrial applications and higher scale renewable green power technologies such as fuel cell, PV cell and wind turbine systems connected to the load. But the traditional multilevel topologies have large components and complex Pulse Width Modulation (PWM) controller leading to reduced harmonics and voltage stress on the load. Therefore, a new topology of a cascaded multilevel inverter employing less number of switches with reduced gate driver circuits and simple control scheme is presented in this paper. A comprehensive MATLAB/Simulink model of a seven-level inverter and the generation of control pulses using multi-carrier-based PWM is evolved and discussed. With the aid of LabVIEW, an experimental prototype is developed and their results are compared with simulation results.

    ABSTRACT: In this research study, direct torque and flux control of an Induction Motor Drive (IMD) using Sliding-Mode Speed Controllers (SMSC) and Fuzzy-Logic Speed Controller (FLSC) are presented to achieve high performance of stator current, electromagnetic torque and motor speed in both transient as well as in steady-state conditions. The PI Speed Controller (PISC) gives good steady-state performance, but poor dynamic response. Therefore, the SMSC is considered to achieve continuous control of motor speed and also electromagnetic torque. Furthermore, FLSC is considered to get high performance, dynamic tracking and speed accuracy at various load torque conditions. The performances of each speed controller techniques are tested under various load toque and speed condition for its robustness. A detailed comparison of different control approaches are carried out in a MATALB/Simulink environment at different operating conditions, such as forward and reversal motoring with no-load, load, sudden change in speed and sudden zero speed.

    ABSTRACT: This paper presents mathematical analysis, design and simulation of a quadratic buck converter used as LED lamp driver, and the performance of the converter is compared with two different control strategies. The objective is to provide tight regulation of the LED current that can operate over a wide range of DC input voltages. The first control strategy is the non-linear Sliding-Mode (SM) current controller, and its design aspects include choice of sliding surface, deriving existing and stability conditions, control parameter selection and their analysis. This paper also throws light on Average Current-Mode (ACM) controller. The operation, modelling, designing and transfer function derivation for the inner current and outer voltage loops of the quadratic buck converter are presented. The tuning of controllers for the ACM controller is done using Bode plots, for achieving desired phase and gain margins. The simulation is done using PSIM software and the results are presented.

    ABSTRACT: An adaptive hysteresis current and voltage control technique for controlling Unified Power Quality Conditioner (UPQC) is proposed in this paper. The novelty of the proposed method is the series and shunt active power filters (APF) present in the UPQC has been controlled by the separate adaptive controllers for reducing the voltage and current perturbations. Here, the adaptive control technique utilises Artificial Neural Network (ANN) and Fuzzy Logic Controller (FLC) for generating the control pulses of the series and shunt APFs. In the adaptive control technique, ANN builds a target hysteresis control data based on the inputs such as voltage and current. By using the hysteresis control data, the control parameters are generated by the FLC. According to the output of FLC, PWM pulses are generated for controlling the APFs. The effectiveness of the proposed adaptive hysteresis control technique is identified by using the comparison analysis with the existing techniques.
