Analysis and Design of Single-Phase Z-Source Inverter with Different PWM Techniques for Standalone PV System

This chapter analyzes the two PWM regulating techniques of Single-phase Z-Source Inverter (ZSI) and recommend the better controlling method for applications involving the conversion of renewable energy sources. The effectiveness of the controlling strategies is assessed in relation to the control strategy’s simplicity, voltage stress across switches and output voltage peak value. The Maximum Boost Control (MBC) method is providing higher voltage gain than Simple Boost Control (SBC) and these results have been evaluated by simulating the circuit in Matlab/simulink.
