摘要
探讨了电力电子装置开关电源中模拟信号隔离传输的意义及各种实现手段,在全面分析比较的基础上提出了串行 D/A 数字隔离传送的方法,并通过在数控开关电源中的典型运用的分析与实验表明该方法可行,能够用于电力电子装置的精确控制。
Based on introduction of the isolated analog signal transmission, the analysis and comparison of a variety of isolated technologies is carried out, and a novel digital isolating method based on serial interface D/A converter is put forward. Finally, based on its typical application in a digital controlled SMPS, the corresponding experiment results show this method can realize high precision control for power electronics installation.
