MOS Controlled Thyristor (MCT) Characteristics Under Advanced Liquid Cooling 932576
The Mos Controlled Thyristor (MCT) is a very promising switch device which combines the high power capability of thyristors and the low energy gate control of a MOS device. The MCT has high voltage and high current capabilities and its power dissipation depends on the losses due to turn-on, turn-off and conduction.
This paper describes the potential of indirect liquid cooling to remove the waste heat generated while a MCT is operating at various power levels and switching frequencies.
An MCT device dissipated 187 W. The switching mode was cooled to keep the junction temperature below 150°C by using the Venturi cooling technique.
