| Abstract |
Due to the non-existence of natural freewheeling paths the commutation in matrix converters is more complicated than in voltage source converters. The proposed interlock-free control for the bidirectional switches where both current directions can be controlled independently is based on the knowledge of the signs of the line to line input voltages and the load current directions. The suggested policy is compared with multi-step commutation methods. Finally some measurement results of the forward recovery effect of new reverse and non reverse blocking IGBTs are presented. |
