一种基于电流路径跟踪的T型逆变器开路故障诊断电压矢量残差估计方法

This article proposes a current path tracking approach that uses a current path state to correlate device status and operating mode of an inverter under normal and abnormal conditions. Based on graph theory, a node-path modeling method is proposed and applied in the T-type inverter topologies. The model reflects system state transitions, given healthy or faulted transistors. Effective conduction p...
