提出了一种简单易行的串联锂离子电池组磁耦合均衡器。该均衡器不使用电压检测电路和多绕组Transformer的二次侧元件，对所有有源功率开关施加相同的占空比。在接通切换间隔期间，均衡器自动地将能量从高电压电池单元传递到低电压电池单元。所提出的均衡器可以有效地减小均衡器系统的尺寸、成本和设计复杂度。
A simple and easy magnetic coupling equalizer for a series-connected lithium-ion battery string is presented. The equalizer applies identical duty cycle to all active power switches without using the voltage sensing circuits and the secondary side components of multi-winding transformer. During the turn-on switching interval, the equalizer automatically transfers energy from the high-voltage battery cells to the low-voltage battery cells. The proposed equalizer can effectively reduce size, cost, and design complexity of the equalizer system.
