基于改进温度准则的IGBT健康状态监测自激短路法研究

The bonding wires and busbars in IGBT modules may have open points and breaks during long-term use, causing changes in short-circuit current. The health status of the IGBT module can be analyzed by detecting and judging the short-circuit current. The self-excited short circuit monitoring technology controls the gate voltage to cause small current short circuits in the IGBT. By detecting the magnit...
