PSPICE modelling and design of a snubber circuit for the matrix converter
International Journal for Engineering Modelling, 2000 In matrix converters one of the basic commutation strategies is the dead time current commutation. Although the application of this commutation strategy is simple and easy, the design of snubber parameters becomes crucial to control the voltage spikes across the switches due to the open circuiting of the motor winding during the dead time.
