Adaptive gate drive control method and circuit for composite power switch
摘要:
Provided is a method of controlling a hybrid switch comprising a first individually controllable semiconductor switch operably coupled in parallel to a second individually controllable semiconductor switch. The first semiconductor switch has a faster switching speed and lower power-processing capability than the second semiconductor switch. A first reference value V1REF for a first default turn-on transition time interval ΔT1 and a second reference value V2REF for a second default turn-off transition time interval ΔT2 are accessed for the controllable hybrid switch, which is enabled and controlled so that it operates in accordance with V1REF and V2REF. The duration of the default ΔT1 and ΔT2 used to control operation of the controllable hybrid switch is dynamically adjusted to compensate for at least one of variations in a current to a load operably coupled to the controllable hybrid switch and environmental conditions at the controllable hybrid switch.
