Abstract:
A solid state power control apparatus includes: (a) at least one IGBT and at least one FET, for supplying current to a load, and (b) a current controller for shutting off the IGBT and FET. The current controller is arranged to start shut off of the IGBT before it starts shut off of the FET. Further, the current controller is arranged to reduce current flow prior to start of the turn off of the IGBT and FET.
