Abstract

Open-switch fault accounts for large proportions among failures in power conversion system. Previously, fault defection methods are carried out by researches from transient period or circuit configuration with complicated algorithms. This paper reveals characteristics of single IGBT open-switch fault in rectifier from perspective of modulation scheme It presents that with a suitable modulation index and modulation scheme, current park's vector diagnosis method can become simple and effective for two-level three-phase AC-DC power converter. In that way, park's vector can be generalized for localizing faults in both inverter and rectifier.
