Abstract

This paper compares the simulated dynamic response of pulse-width modulated Z-source inverter (ZSI) and PWM Z-source dc-dc converter (ZSC) to step change in input voltage and duty ratio. The principle of operation of PWM ZSI is presented. The different active and null states, and their importance, of the ZSI have been highlighted. The reduction of ZSI to ZSC for the purpose of dynamic analysis is explained. Steady-state analysis of the PWM ZSC has been briefly presented. Transient simulation results of response of PWM ZSI and PWM ZSC to step changes in input voltage and duty ratio are presented.
