A power electronic inverter is developed for a high-frequency induction heating application. The application requires up to 160kW of power at a frequency of 1OOkHz. This power-frequency product represents a significant challenge for today's power semiconductor technology. Voltage source and current source inverters both using ZCS or ZVS are analyzed and compared. To attain the level of performa...

This paper explores the advantages and implementation of Digital Signal Processing (DSP) TMS 320F2812 to generate gate pulses. The main features of this DSP are elaborated. The technique to obtain gate pulses in different pulse width modulation methods in order to control three-phase voltage source inverter is explained systematically. The steps needed to develop the program are highlighted in ...

In the last decades, the increasing restrictions imposed on the exhaust emissions from internal combustion engines have given a strong impulse toward the development of electric propulsion systems for automotive applications. The goal of electric and hybrid vehicles is the reduction of global emissions and global warming which in turn leads to a decrease of fuel resources exploitation. In this ...

This paper presents a new step-up DC/DC converter topology to be used for distributed energy systems. The topology contains a voltage-fed quasiZ-source inverter with continuous input current, a high-frequency step-up isolation transformer and a voltage doubler rectifier. Main operating modes of the converter are explained and steady state analysis of the voltage-fed quasi-Z-source inverter is p...

In this paper, we present a comparative assessment of Space Vector Pulse Width Modulation (SVPWM) and Model Predictive Control (MPC) for two-level three phase (2L-3P) Voltage Source Inverter (VSI). VSI with associated system is subjected to both control techniques and the results are compared. Matlab/Simulink was used to model, simulate and validate the control schemes. Findings of this study s...

This paper presents the performance analysis of DFIG based off shore wind farm feeding to large power system through a hybrid HVDC link. The hybrid HVDC link consists of a line commutated converter based inverter and voltage source converter based rectifier. The active and reactive power of off shore station is controlled using voltage source converter based rectifier controller and the dc line...

In this study, two types of multilevel convertors, cascaded multilevel inverter with separate DC sources and diode clamped multilevel inverter with common DC source are modeled and compared in the case of feeding of an induction motor. Here, SHEPWM technique is used as the switching strategy. Also a new variable torque feedback control on modulation index is presented, to preserve the induction...
