这是一个电力电子设备故障诊断的一个硕士# 39；的问题。

这是一篇有关电力电子装置故障诊断的硕士论文，以整流电路为例，开发了一个以频谱分析和神经网络为方法的缺相的故障诊断，并用DSP来实现了。论文思路清晰，逻辑强，实验结果可靠，值得期待。-This is a power of the fault diagnosis of electronic devices in a master"s thesis in rectifier circuit for example, development of a spectrum analysis and neural network method is the lack of fault diagnosis, and use of the DSP to achieve. Papers clear thinking, logic strong, reliable results should be worth the wait.
