Abstract :
In this paper a matrix converter with a special circuit is presented. It works so that no overvoltage can be produced by an interruption of an input phase when operating with inductive load current. Also a switching off of one or more semiconductors of the inverter matrix can not produce the high voltage spikes by using the overvoltage protection circuit. This matrix converter works without any complicated commutation strategy. This reduces the measurement and control complexity significantly. Also the weight, the volume and the cost are reduced.
