Modeling, simulation and testing of MCT under zero voltage resonant switching

An MCT (MOS controlled thyristor) model based on a two-transistor SCR (series resonant converter) model is developed which is useful in determining the behavior of the MCT in different circuits. The model is found to work successfully in PSPICE simulations under zero voltage square wave and resonant switching. An experimental prototype was built, tested, and compared with the simulation results. A major part of the prototype construction is to investigate the gate drive requirements for the MCT. The model shows fair correspondence to experimental behavior found in both hard and soft switched circuits.<
