Abstract: One embodiment is a uninterruptable power supply (UPS) system including a utility disconnect switch (UDS) coupled with an input line and an output line and structured to selectably connect and disconnect the input line and the output line. The UDS includes a semiconductor switching device connected between the input line and the output line, a surge arrester coupled in parallel with the semiconductor switching device, a dynamic voltage balancing device and a static voltage balancing device which are coupled in parallel with the semiconductor switching device.

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.
