摘要

介绍了一种适用于高压隔离系统的开关电源(SMPS)。本文的SMPS由一个二极管全波整流器和一个全桥LLC谐振变换器组成。在LLC谐振变换器的变压器中实现了输入和输出的隔离。介电强度一般由爬电路径长度和插入气隙和绝缘子等间隙决定。本文所设计的变换器工作在开关频率140khz左右，最大额定功率500w，最大输出电流21a，输出电压24v。通过仿真验证了该转换器的有效性。

Switched Mode Power Supply with High Isolation for High Voltage Applications

This paper introduces a switched mode power supply (SMPS) for power systems that requiring high voltage isolation. The SMPS in this paper consists of a diode full wave rectifier and a full-bridge LLC resonant converter. Isolation of input and output is achieved in the LLC resonant converter's transformer. Dielectric strength is generally determined by the length of creepage path and clearance like insertion the air gap and the insulator. In this paper, the proposed converter operates about 140-kHz switching frequency, maximum power rating of 500-W, maximum output current of 21-A, and output voltage of 24-V. The proposed converter was verified by simulation.
