本文介绍一种新的三相全控桥调压电源同步触发方案。在这一新模式中，用光电隔离器代替传统的三相同步变压器使同步方式发生了根本变化，光电隔离器输出的信号经整形后数字信号的方式进 This article describes a new three-phase full control bridge power supply synchronization trigger scheme. In this new model, the use of optoelectronic isolators instead of the traditional three-phase synchronous transformer to make a fundamental change in the synchronization method, the opto-isolator output signal by shaping the digital signal into
