提出了一种并联电源模块的均流电路。该接口电路使独立的和不相同的功率模块的输出在容错或连接电源系统中均等地分担负载电流。电源模块之间不需要CS互连。在所提出的接口电路中，并联功率模块的输出电流通过测量电感器的电压降来感测，并以滞后方式进行控制。实现了一种实用的CS接口电路。实验结果与理论分析相吻合。
This paper proposes a current-sharing (CS) circuit for parallel power modules. The interface circuit enables the outputs of independent and nonidentical power modules to equally share the load current in a fault-tolerant oring-connection power supply system. No CS interconnections among the power modules are required. In the proposed interface circuit, the output currents of the parallel power modules are sensed by measuring the inductor voltage drops and controlled in a hysteresis manner. A practical CS interface circuit is implemented. The experimental results are in good agreement with the theoretical analyses.
