一种新型三相电流源变流器短路故障诊断方法

In order to improve the reliability of current source converters, a new fault diagnosis method that can identify the single-switch and double-switch short-circuit faults is proposed in this article. It only needs an output current signal. First, the amplitude and phase of the output current vector are calculated in a real-time manner. Second, the amplitude is compared with a diagnosis threshold. C...
