    ABSTRACT: An AC/AC matrix converter is an array of power semiconductor switches that connects directly a three-phase AC source to another three-phase load. It can convert an AC power source with certain voltage and frequency to another AC load with variable voltage and variable frequency directly without a DC-link and bulk energy storage component. Classical modulation methods such as the Venturini method and the space vector modulation method using AC-network maximum-envelope modulation, implement matrix conversion successfully. However, they also cause very high total harmonic distortion (THD). A novel approach, the sub-envelope modulation (SEM) method, is presented to reduce THD of matrix converters effectively. The approach is extended to an improved version of matrix converters and the THD can be reduced further. The algorithm of the SEM method is described in detail. Simulation and experimental results are also presented to verify the feasibility of the SEM approach. The results will be very helpful for industry applications

    ABSTRACT: A novel pulse-current converter topology for induction heating is introduced. The possibility and expediency of the pulse current for induction heating have been demonstrated. The converter comprises the input filter, input reactor, bridge rectifier, two power switches, two coils mutually coupled with the input reactor and the heating inductor (load), where the output power is controlled by a switching frequency. The steady-state analysis of the converter operation, its computer simulation and the experimental verifications on the converter model have been performed. The simulation on the computer and the experimental results are shown to be in good agreement with the theoretical results. The following two goals have been achieved: (a) the analysis of the heating process with the pulse current has been performed; and (b) the appropriate scheme of the pulse-current supply has been developed. The proposed scheme fulfills the requirements of modern power supplies: sine form of the input current, unity power factor, soft commutation and a wide range of output power. The proposed configuration can be used for heating, annealing, melting and hardening in the power range of 250-300 kW

    ABSTRACT: The detection of broken-rotor-bar faults based on common steady-state-analysis techniques, such as the fast Fourier transform (FFT), is known to be significantly dependent on the loading conditions of the induction motor. At light load, it is difficult to distinguish between healthy and faulty rotors because the characteristic broken-rotor-bar fault frequencies in the stator current are very close to the fundamental-frequency component and their amplitudes are small in comparison. As a result, detection of broken bar faults and classification of the fault severity under light load is very difficult. To overcome this problem, the analysis of the envelope of the transient starting-current waveform using the wavelet-transform has been investigated. The envelope extraction is used to remove the strong fundamental-frequency component, which would otherwise overshadow the characteristic differences between a healthy motor and a faulty motor with broken rotor bars. The wavelet-transform results are processed to develop a normalised parameter called the `wavelet indicator' which is sensitive to the presence of broken-rotor-bar faults. The results are verified using tests on machines with a varying number of broken bars, as well as partially broken rotor bars, over a wide range of loading conditions. The effects of initial rotor position and supply imbalance are also investigated

    ABSTRACT: A systematic procedure to synthesise power gyrators for variable switching frequency operation is presented. Based on the gyrator equations, topological constraints are first established and two types of gyrators, i.e. G and R, are defined. A boost converter with an output filter and the Cuk converter are shown to have the unconditionally stable characteristics of G-gyrators with a controlled input current whereas a buck converter with an input filter and also the Cuk converter are shown to behave as G-gyrators with a controlled output current if damping networks are inserted and certain stability conditions are accomplished. Similarly, a boost converter with an output filter is shown to behave as a power R-gyrator with stable dynamics

    ABSTRACT: An advanced controller design for a sensorless interior permanent-magnet synchronous motor control system is proposed. A maximum torque/ampere control algorithm is used to improve the torque performance of the drive system. In addition, an adaptive controller combined with the maximum torque/ampere control is proposed to obtain a good transient response and a good load disturbance rejection capability. The proposed control method can be applied to both a sensorless adjustable speed control system and a sensorless position control system. Using the Lyapunov stability theory and Barbalat's lemma it is shown that the closed-loop sensorless control system is an asymptotical stable system. A 32-bit digital signal processor is used to execute the rotor position estimation algorithm and the control algorithm. Experimental results validate the theoretical analysis and show the correctness and feasibility of the proposed system

    ABSTRACT: The speed-sensorless vector-controlled induction-motor drive is superior to the conventional vector-controlled induction-motor drive in terms of drive cost and reliability. In speed-sensorless control, one common practice is to estimate the flux position from the terminal voltage and current using a stator-voltage model. The accuracy of estimated flux position decides the performance of the vector-controlled drive. However, the performance is limited by the DC-drift problems that prohibit the use of open integration of the flux-producing voltage component for flux estimation. The paper proposes a flux-estimation method that gives the effect of open integration along with an inherent error-decaying mechanism to resolve the DC-drift problem. A stator-resistance-adaptation method is also incorporated in the flux estimator, which makes the flux-position estimation independent of resistive parameters of the motor. Using this flux-estimation algorithm, a rotor-flux-oriented speed-sensorless speed-control scheme of induction motor is proposed. The scheme is both simulated and experimentally verified

    ABSTRACT: An integral variable-structure grey control for a magnetic levitation system for position tracking is presented. The sliding-mode control is insensitive to system uncertainties and disturbances when it is within expected limits. It produces chattering when uncertainty values are overestimated, or steady-state error when underestimated. The method uses a mathematically simple and computationally efficient grey compensator for the integral variable structure controller to reduce chattering and steady-state error. The stability of this magnetic levitation system is proven by using the Lyapunov function. The experimental results verify that the proposed controller is valid for a magnetic levitation system

    ABSTRACT: The parallel operation of several low-capacity inverters is better than a singular high-capacity inverter owing to the advantages of better extensibility and reliability. A simplified control method for parallel-connected inverters is proposed, which can balance the current distribution among the parallel-connected inverters with no interconnected communication lines. To verify the performance of the proposed control method, a prototype consisting of two inverters has been developed. The experimental results verify that the performance of the proposed control method is as desired

    ABSTRACT: V-belt-linked continuously variable transmissions (CVTs) find extensive use in both internal-combustion-engined and electric scooters. The CVTs are used to increase the starting torque and also extend the range of the operating speed of the vehicles. Unfortunately, the efficiency of a CVT is relatively low due to friction effects and the alternative techniques based on flux weakening control are both complex and costly to implement. To circumvent these problems a multispeed winding is designed that is able to increase the starting torque at low speeds and extend the constant-power speed ratio for small and midsized brushless DC motors. Moreover, in order to increase the reliability of the drive system, a cost-effective sensorless control algorithm is developed. The commutation signals can be directly extracted from the average terminal voltages of the motor using simple RC circuits and comparators. This means that the sensorless commutation can be implemented by simply using low-cost CPLDs or microcontrollers. The proposed approach is particularly suitable for application to cost-sensitive electric vehicles such as wheel chairs, bikes and scooters and also hybrid electric scooters. A theoretical analysis of the pattern is performed and various experiments are conducted to evaluate the effectiveness of the proposed method

    ABSTRACT: Analysis and design of a three-phase AC-to-DC resonant converter is considered. The power factor of the three-phase AC input line diode bridge rectifier is improved by injecting high-frequency current. The three-phase AC-to-DC resonant converter is operated at frequencies above the resonant frequency. The analysis of the converter is carried out using different operating modes in one switching cycle of the resonant inverter. The design of the AC-to-DC resonant converter is discussed step by step. An experimental prototype of a 3 kW, 500 V output power and operating above 300 kHz has been developed in the laboratory. The proposed three-phase AC-to-DC resonant converter has high power factor, low total harmonic distortion and high efficiency. It requires narrow variation in switching frequency to regulate the output voltage

    ABSTRACT: The radial force density harmonics and vibrational characteristics of a three-phase modular permanent magnet brushless AC machine is investigated. It is shown that, owing to the presence of a large number of low- and high-order stator space harmonic magnetomotive forces, modular machines are more likely to exhibit higher low-frequency vibrations than conventional permanent magnet brushless machines. Experimental results support the analysis and its findings

    ABSTRACT: A systematic procedure to synthesise power gyrators for constant switching frequency operation is presented. The equivalence between ideal sliding dynamics and PWM zero dynamics is used to derive the control law of the duty cycle. As a consequence, any power gyrator with stable behaviour in sliding-mode results in a stable equivalent gyrator at constant switching frequency with the same stability conditions. The design of a PWM G-gyrator with controlled output current based on a buck converter with input filter illustrates the procedure. Simulations and experiments are in good agreement with the theoretical predictions

    ABSTRACT: A load simulator with power-recovery capability is proposed. The load simulator consists of a converter-inverter set with a DSP controller for system control and PWM pulse generation. The converter operates as a universal load to model the linear load and the nonlinear load, while the inverter feeds the energy back to the power source with harmonic compensation. The operation of the proposed system has been analysed through simulations with PSCAD/EMTDC, and the feasibility of hardware implementation confirmed through experimental work with a 20 kVA prototype. The load simulator can save the electrical energy used in testing performance of the power quality compensator and power equipment

    ABSTRACT: A novel soft-switching PWM utility frequency AC to high-frequency AC power conversion circuit, incorporating boost-half-bridge inverter topology, which is more suitable and acceptable for cost effective consumer induction heating applications, is presented. The operating principle and the operation modes are described using equivalent circuits with the operating voltage and current waveforms. The operating performances are illustrated and evaluated, including the power regulation and power conversion efficiency against duty cycle characteristics based on the power dissipation as compared with those of the previously developed high-frequency inverter. The practical effectiveness of the power converter is substantially proved, based on experimental results from a practical design example

    ABSTRACT: A TSK-type recurrent fuzzy network (TSKRFN) control system is proposed to control the position of the mover of a field-oriented control permanent-magnet linear synchronous motor (PMLSM) servo drive system to track periodic reference trajectories in this study. The proposed TSKRFN combines the merits of self-constructing fuzzy neural network (SCFNN), TSK-type fuzzy inference mechanism, and recurrent neural network (RNN). Moreover, the structure and the parameter learning phases are preformed concurrently and online in the TSKRFN. The structure learning is based on the partition of input space, and the parameter learning is based on the supervised gradient-descent method using a delta adaptation law. Furthermore, all the control algorithms are implemented in a TMS320C32 DSP-based control computer. The simulated and experimental results due to periodic reference trajectories show that the dynamic behaviour of the proposed TSKRFN control system is robust with regard to uncertainties.
