Operating currents are fairly high, in excess of 1500 A and switching voltage up to 3000 V.[14] The IGBT has reduced input capacitance compared to MOSFET devices which improves the Miller feedback effect during high dv/dt turn on and turn off.[15] MOS-controlled thyristor (MCT) The MOS-controlled thyristor is thyristor like and can be triggered on or off by a pulse to the MOSFET gate.[15] Since the input is MOS technology, there is very little current flow, allowing for very low power control signals.
