| Abstract |
MCT is a new power device which combines the lower on state voltage and the higher current density of the thyristor together with the simplicity of the MOS gate turn-on and turn-off. ZVS and ZCS soft-switching conditions are encountered in several resonant converter configurations. The purpose of this paper is to present a behaviour analysis of the MCT in ZVS and ZCS soft-switching modes. Two test circuits, allowing the above switching conditions in single shot mode and easy adjustment of analyzing parameters such as transient turn-on voltage spike as a function of dI/dt for ZVS and transient turn-off current spike and tail current as a function of dV/dt for ZCS, are proposed. Inside physical description of the MCT in each switching mode is also presented, to provide usefull insights into the physics of the device with a view to obtaining the best possible performances. |
