介绍一种应用于驱动大功率电力电子器件的分布式隔离辅助电源系统的二次侧。辅助电源系统分为高压输入侧和高压隔离侧。采用新的变压器绕制,确保高的电气隔离,解决电路干扰通过辅助电源传导的问题,切断了干扰的该传递路径,并且给出了电路和市场上的普通辅助电源隔离效果的比较。实验结果证明了电路在阻断干扰上的优势。

The second-side of an isolated distributed power supply system with high-voltage isolation was proposed, which was used to drive high power electronics devices. The auxiliary power supply system was divided into two parts, high-voltage input side and high-voltage insolated side. The new transformer winding was adopted to ensure the high-voltage isolation, which solved the problem that interference conducted through accessory power supplies. Finally, a comparison between the proposed circuit and a common power supply circuit was presented. The performance of the circuit is verified by experimental results.
