Three switch quasi Z-source series resonant inverter

Abstract

This paper proposed new topology of quasi Z-source series resonant inverter by using three switches. The main advantages of new three switch quasi Z-source series resonant inverter is simple control strategies, widely varying input voltages, obtain a sine wave output voltage in high frequency. It consists of quasi Z-source boost converter with single switch and series resonant inverter. Moreover obtain a required frequency by setting series resonant inverter frequency. Theoretical analysis of three switch quasi Z-source series resonant inverter presented. The proposed inverter is a wide range of voltage gain. It is suitable for applications in photovoltaic (PV) systems, fuel cell. A simulation result is presented to verify the proposed inverter concept and theoretical analysis.
