This paper presents detailed modeling principles of a typical Inductive Power Transfer (IPT) module using the Matlab/Simulink software. The presented model is based on AC-AC Matrix Converter that are implemented by four MOSFET switch followed by resonance LC circuit. The presented models are designed with user-friendly blocks from the Simulink bloc...

This paper presents a novel approach for the field programmable gate array (FPGA)-based hard co-simulation of typical inductive power transfer (IPT) system. The implemented control algorithm is in an environment of the Spartan-3A/3AN (FPGA) kit board, while the power section and the load are simulated in Matlab/Simulink environment. An applicable e...

Applying traditional circuit analysis techniques, this paper proposes a new approach to model the steady state operating conditions of the DC/DC buck-boost power converters. The developed approach can be more or less considered new because it is not present in the literature, sometimes it can be considered general because it is valid for the other...

In this paper an experimental prototype pulse width modulated (PWM) sliding mode controller (SMC)was applied to a DC/ DC buck-boost (BB) converter. The implementationprocedure is given in detail. Both the static and dynamic performances of the experimental system are tested in the Lab.Agood voltage regulation is obtained and the control scheme seem...

Direct torque control (DTC) of three phase induction motor uses the motor stator resistance to estimate the stator flux. The variation of stator resistance due to changes in temperature or frequency deteriorates the performance of DTC controller by introducing errors in the estimated flux linkage and the electromagnetic torque. A fuzzy based stator...

Direct drive motors lre used as rctuators in numerous applications in which they must rotate rt low speeds .r"itf, ftigh toique and low torque ripple' Various types ofvernier motorsiave been studied recently. The IIB type vernier motor is one of them. Its rotor structure is the same as in a HB type stepping motor but has a field winding at the roto...

This paper presents a new simulation soft switching three level inverter using MATLAB program. This circuit uses two identical Auxiliary Active Resonant DC Link (ARDCL) snubbers connected to the high voltage DC bus line ofthreeJevel inverter.

This paper presents a method for improving the speed profile of a three phase induction motor in direct torque control (DTC) drive system using a proposed fuzzy logic based speed controller. A complete simulation of the conventional DTC and closed-loop for speed control of three phase induction motor was tested using well known Matlab/Simulink soft...

The paper dells with a modified experimental prototype for pulse-width modulation (PWM) sliding mode control (SMC) applied to a DC-to-DC-boost converter operated in continuous conduction mode (CCM). Experimental results show that the proposed control scheme provides good voltage regulation and is suitable for common DC-to-DC conversion purposes. Th...

Among all control methods for induction motor drives, Direct Torque Control (DTC) seems to be particularly interesting being independent of machine rotor parameters and requiring no speed or position sensors. The DTC scheme is characterized by the absence of PI regulators, coordinate transformations, current regulators and PWM signals generators. I...

The paper presents a proposed scheme for fast braking of induction motor drive system. The proposed braking strategy is based on the injection of an AC voltage to the rotor winding from three-phase SVPWM inverter during braking. The injected voltage must have the same frequency, same phase shift and opposite in direction to the rotor induced voltag...

Control of DC/DC boost converter is a complex task due to the nonlinearity in the converter and that introduced by the external changes. This paper describes a robust sliding mode controller for the control of DC/DC boost converters. As well as, dynamic equations describing the boost converter are represented. Also, sliding mode controller is model...
