MOS-controlled thyristor : ウィキペディア英語版 | MOS-controlled thyristor
An MOS-controlled thyristor (MCT) is a voltage-controlled fully controllable thyristor. They were invented by IEEE. MCTs are similar in operation to GTO thyristors, but have voltage controlled insulated gates. They have two MOSFETs of opposite conductivity types in their equivalent circuits. One is responsible for turn-on and the other for turn-off. A thyristor with only one MOSFET in its equivalent circuit, which can only be turned on (like normal SCRs), is called an MOS-gated thyristor. Positive voltage on the gate terminal with respect to the cathode turns the thyristor to the on state. Negative voltage on the gate terminal with respect to the anode, which is close to cathode voltage during the on state, turns the thyristor to the off state. == External links ==
