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.
