New commutation method of a matrix converter

In this paper an extended matrix converter which is tolerant against an interruption of an input phase when operating with inductive load current is presented. Also a switching off of one or more semiconductors of the inverter matrix can not interrupt the inductive load current. This extended matrix converter works without any complicated commutation strategy and without any of the well known protection circuits. This reduces the measurement and control complexity significantly, whereby the risk of failure in the control strategy decreases.
