Modified Space Vector Pulse Width Modulation for Z-Source Inverters

This paper presents a Modified control method for Space Vector Modulated (SVM) Z Source inverters. Proposed algorithm provides a modified voltage vector with single stage controller having one degree of freedom wherein traditional controllers have two degrees of freedom. Through this method of control, the full utilization of the dc link input voltage and keeping the lowest voltage stress acros...

Multilevel Inverters Based On Space Vector Pulse Width Modulation Technique

In this paper, a simplified space–vector pulse width modulation technique for multilevel inverters is proposed. This method is based on the simplification of the space–vector diagram of a five level inverter into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Hence, the algorithm of five level space-vector pu...

Performance of Sinusoidal Pulse Width Modulation based Three Phase Inverter

In this paper a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. . The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. The fundamental component of the three-phase line-to-line voltage is increased by about 15 percent above than that of the conventional sine-wave inverter. The sinusoidal PWM switching scheme allo...

Space Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
