摘要: The series connection of insulated gate bipolar transistor (IGBT)/diode devices allows the operation at voltage levels higher than rated one IGBT/diode. However, due to individual parameter differences series-connected IGBT/diodes, it is difficult ensure a proper balance between them, and transient or steady-state unbalances could cause failure these devices. This paper presents an active driver developed by authors that suitable for IGBTs. proposed achieves IGBT/diode effectiveness control method has been experimentally validated, promising results have obtained.
