Research of Switched Inductor Boost Converter Based on Topology Combination

Abstract

According to the voltage gain of boost converter at the photovoltaic inverter system, a high gain switched inductor boost converter is proposed in this paper by analyzing and studying the voltage gain ability of traditional switched inductor boost converter which improves the switched inductor three-terminal network topology. The working principle and working characteristics of the designed boost topology are analyses in detail, and the corresponding mathematical model is established. Compared with the traditional converter, the proposed converter has some advantages which improving the boost ability and decreasing the voltage stress of the switch tube. Moreover, the simulations are shown to verify the correctness of the theoretical analysis.
