摘要
根据高电压宽输入电力电子变换器的供电需求,设计了一种双管反激辅助电源。分析了双管反激变换器的工作原理;针对宽输入电压范围带来的电流环次谐波振荡问题,设计了斜坡补偿电路;提出了一种电流控制型双管反激变换器的低损耗启动电路。实验证明所设计的高电压宽输入双管反激辅助电源有效可行。
According to power supply requirements of power electronic converter with high-voltage and wide-range input, a double-tube flyback auxiliary switching power supply was designed. The operation principle of the double-tube flyback converter was analyzed. In order to solve the problem of current loop subharmonic oscillation from the wide-range input voltage, a slope compensation circuit was designed. A low-loss start-up circuit of current-mode double-tube flyback converter was presented. Experiments show that the design of the auxiliary switching power supply for power electronic converter is reliable and feasible.
