Abstract: A switching module, intended to be used in a medium or high voltage DC breaker or a DC current limiter, includes at least one power semiconductor switching element, a gate unit arranged to turn the at least one power semiconductor switching element on and off, respectively, according to a switching control signal, and an energy storage capacitor arranged to provide power to a power supply input of the gate unit. The switching module further includes a power transformation device arranged to receive an optical power signal, to transform the optical power signal into an electrical power signal and to provide the electrical power signal to the energy storage capacitor.
