摘要：采用电力电子标准模块(PEBB)构建电力电子系统，是电力电子系统集成的目标，电力电子标准模块间的同步是保证系统正常工作的重要前提。将时钟恢复技术应用于电力电子系统集成，设计了一个软件锁相环，实现了模块间的时钟同步。对一个基于PEBB的三相电压源逆变器进行了实验，实验结果表明，各个PEBB之间实现了时钟同步。

Abstract: The goal of power electronic system integration was to build power electronic system by Power Electronic Building Block, the synchronization was the premise to insure the system working normally. A software phase locked loop was designed with timing recovery applied in power electronic system integration to realize the clock synchronization between power electronic building blocks. By the experiment of 3 phase VSI, it show that the clock synchronization between power electronic building blocks had been realized.
Key words: power electronic system integration; power electronic building blocks; timing recovery; clock synchronization
