Abstract

This paper presents a new non-isolated high gain, boost converter for power electronic applications, such as renewable energy and electric vehicle systems. The converter uses a coupled inductor and switched capacitor to achieve the high step up voltage requirements. Importantly, the structure of the high voltage side, together with the switched capacitor, reduces the voltage stress across the diodes; thus enhancing the capability of the circuit. Furthermore, the semiconductor switch voltage stress is reduced to less than one third of the output voltage. The main switch achieves zero current switching (ZCS) turn-on performance and all diodes achieve (ZCS) turn off reducing reverse recovery losses. As a result, the circuit exhibits high efficiency performance; which is essential in most modern power electronic applications. In this paper, the operational principle and performance of the proposed converter is presented and validated experimentally with a 250 W, 20 V input voltage / 190 V output voltage prototype circuit.
