The two-phase SZS inverter consists of four switches and two Z-source networks. The buck-boost functionality achieved without the presence of shoot-through phenomenon is the major advantage of the two-phase SZS inverter. In the two-phase SZS inverter structure, there are two blocks of single-phase SZS circuits. Each single-phase SZS inverter block consists of two switches and one Z-source network. In each SZS inverter block, the switches are operated complementarily. The voltage gain of the single-phase SZS circuit block is non-linear in nature and a Modified Sinusoidal Pulse Width Modulation (MSPWM) technique is employed for generating the switching pulses. The MATLAB/Simulink results are presented to demonstrate the characteristics of the two-phase SZS inverter. © 2018 IEEE.Full-Bridge (FB) InverterModified Sinusoidal Pulse Width Modulation (MSPWM)Renewable Energy Sources (RES)Semi-Z-Source (SZS) inverter
