电池组均衡充电用反激变换器设计方法的研究

Equalization charging of the battery pack is one of the most effective methods to eliminate the battery inconsistency. According to the requirements of battery charging system, a flyback converter for equalization charging was investigated. The converter consisted of input rectifier and filter circuit, flyback circuit, output filter circuit and feedback control circuit. Their design principle was discussed and corresponding parameters of the converter was calculated. Simulation and test results verified the effectiveness of the design method.
