A comparative analysis of PWM techniques for ZSI in application of electric vehicles

Abstract EN

This paper focus on, three pulse width modulation (PWM) techniques such as simple boost control (SBC), maximum boost control (MBC) and constant boost control (CBC) are analyzed for impedance source inverter (ZSI) topology, because of its boosting capability of applied input voltage, compared with traditional voltage or current source inverters.

For the purpose of comparison, the ZSI topology is simulated by using different PWM techniques for the same input voltage, switching frequency, peak voltage of inverter and duty ratio.

These simulations have been developed for ZSI for electric vehicle applications.

The comparison results show that constant boost control technique is a suitable PWM method for ZSI topology.
