摘要
Commutation method of an electronic power converter phase with reverse-conducting IGBTs The invention relates to a method for commutating from a reverse-conducting IGBT (T1) operated in the diode mode to a reverse-conducting IGBT (T2) operated in the IGBT mode. According to the invention the reverse-conducting IGBT (T1) operated in the diode mode is turned off only at the instant a current starts to flow in the reverse-conducting IGBT (T2) operated in the IGBT mode. Accordingly said commutation method is event-driven, as a result of which it is less sensitive to poorly toleranced operating times.
