Boost DC-DC Converter Based Z-source Inverter with High Frequency Link

Abstract

This paper proposes a new topology of DC-DC converters with high gain of boost. The suggested circuit consists of Z-source inverter, high frequency transformer and diode rectifier. In this topology the output voltage amplitude is not limited to DC voltage source and transformer turn ratio similar to traditional high frequency DC-DC converters and can be regulated with Z network shoot-through state control. Besides, it is more reliable
