一种抑制母线电压尖峰的软开关准Z源变换器
A Soft Switching Quasi-Z-source Converter for Suppressing Voltage Spikes of Busbars
摘要
Abstract
Aiming at the problems of high voltage spikes and hard switches of quasi-Z-source topologies,a soft-switching quasi-Z-source converter with the characteristics of high voltage gain which could effectively suppress the high voltage spikes of the bus bar was introduced. The voltage gain was increased by using coupling elements instead of the original inductor,and a diode was added to pass the leakage inductance energy to the load and the topological efficiency was improved. The main switch the soft-switching characteristics was achieved,and the reverse recovery diode problem was effectively alleviated. Based on the theoretical analysis,a 1 kW prototype was made. The experimental results show that the working process and the final result are in good agreement with the theoretical analysis and simulation results,and with stable performance and good efficiency.关键词
