摘要
为了消除匝数比大的变压器中存在的浪涌电流现象,在高升降压比双向DC-DC转换器中采用了吸收充电能量的有源箝位回路.对其静态和动态特性的理论分析和实验结果表明:开关电源输出端电压发生线性增长,有效抑制了电流浪涌现象.
An active-clamp circuit is presented to avoid the surge-current in buck-boost converter with large-turns-ratio transformer, which is used as a bidirectional DC-DC converter with a high conversion ratio. The theoretical analysis and experimental results of steady-state and dynamic characteristics of it show that the output voltage linearly incremented and successfully avoided the surge-current phenomena.
