Simulation study of pulse width modulation schemes for three-phase impedance source inverter

To avoid a short circuit of the input direct current (DC). source, 3-phase inverter cannot run two switches in same leg at time, and it always operates buck mode, with output voltage being less than voltage. The Impedance source features feature that allows both one to operate can buck/boost which means be greater depending on shoot-through time. In literature, there are few pulse width modulation (PWM) techniques for control. This research includes simulation study as well an examination existing PWM schemes proposal TESVPWM inverters. performance has evaluated using total harmonic distortion fundamental components, validating by findings.
