This study presents simulation and experimental verification of solid-state switch overvoltage protection. The switching device is composed of two antiparallel connected forced commutated semiconductor valves and in analysed case has been used as a low-voltage solid-state bypass switch of UPS system. The aim is to identify the value of overvoltage induced on switch terminals and surge energy during an instance of current turn-off in line with inductive impedance. Afterwards determine optimal solution that protects such a power electronics device. As a protection solution configurations and types of surge arresters have been examined. All simulations have been conducted using PSCAD software package on the model especially prepared for this purpose.
