摘要：
In the process of solar energy development and utilization, Boost converter can achieve high voltage Boost ratio, but there is a problem of high voltage stress of switching devices. In order to reduce the switching device voltage stress a low stress high gain Boost converter basic structure is proposed，which reduces the voltage stress while increasing the voltage gain. In order to better apply to a variety of boosting situations，four types of boosting units，namely secondary Boost network，switched inductor network，switched inductor-capacitor network and quasi-Z source network，are replaced with their energy storage inductors to obtain a class of low-stress high-gain Boost converter. The operating characteristics of the high-gain Boost converter replaced by using quasi-Z source network are analyzed and compared with the same type of converter. Finally，the correctness and feasibility of the theoretical analysis of the proposed converter are verified by using Matlab/Simulink simulation software and experimental prototypes. © 2024 Science Press.
