摘　　要：交流伺服驱动器内部需要多路隔离的电源,本文采用PI公司的DPA-switch集成开关电源芯片和高频变压器设计多路输出隔离的特种高频电源。该电源具有效率高,输出电压稳定,纹波小,体积小、重量轻、成本低等特点。Since the multi-output isolated power supply is required in the AC servo driver, a special multi-output isolated high frequency power supply is designed by using DPA-switch integrated switch power supply chip available from PI company and high frequency transformer. The power supply is featured with high efficiency, stabilized out- put voltage, small ripple, small size, light weight, low cost, etc.
