Abstract

Abstract: This paper proposed a Boost cascaded high gain DC/DC converter and applied it to photovoltaic power generation systems.The converter utilizes Boost circuit cascading technology to provide high voltage gain with a simple structure and no complicated control strategy.In this paper,the working principle and performance characteristics of the proposed converter were analyzed.The correctness and feasibility of the theory were verified by the simulation model in PSIM environment and an experimental prototype with power of 400 W.The results show that the efficiency of the proposed converter in rated condition can reach 92.1%.

Key words: photovoltaic power generation, cascaded, DC/DC converter, high gain
