Abstract : The Voltage Source Converter and the Current Source Converters have the limitations that either they buck or boost the voltage but cannot buck-boost. Quasi Z-source DC-DC converter has an impedance network which performs buck-boost operations. In Quasi Z-Source DC-DC converter the input current is continuous and also the voltage stress across the switches is less. The Quasi Z-Source can boost the input voltage using reduced passive component with improved reliability and reduce cost. Compared to the existing DC-DC converter circuits, they reduce in-rush and harmonic current. Therefore this paper aims at a soft switched Quasi Z-source Converter (qZSC). The simulation results for the proposed configuration are also presented in this paper.
