Abstract: A solid state switch for connecting and disconnecting an electrical device has at least one FET-type device and at least one thyristor-type device coupled in parallel to the at least one FET-type device. A gate driver is operative to send gate drive signals to the at least one FET-type device and to the at least one thyristor-type device for providing current to the electrical device. The gate driver is constructed to control a split of the current as between the at least one FET-type device and the at least one thyristor-type device.
