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。
交流伺服驅動器內部需要多路隔離的電源，本文採用PI公司的DPA—switch集成開關電源芯片和高頻變壓器設計多路輸齣隔離的特種高頻電源。該電源具有效率高，輸齣電壓穩定，紋波小，體積小、重量輕、成本低等特點。
교류사복구동기내부수요다로격리적전원，본문채용PI공사적DPA—switch집성개관전원심편화고빈변압기설계다로수출격리적특충고빈전원。해전원구유효솔고，수출전압은정，문파소，체적소、중량경、성본저등특점。
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.
