Abstract: High voltage direct current (HVDC) networks are effective keys for the incorporation of considerable scale of distributed resources with the utility power networks. This fast progress of HVDC power networks give rise to the increasing interest for finding an efficient and reliable HVDC circuit breaker. The rapid proceed in electronic switches, specially the insulated gate bipolar transistor (IGBT), allow to be vastly applied in the evolution of a quite efficient static circuit breaker. This work suggest a ± 400 kV static HVDC circuit breaker using IGBT. The suggested circuit breaker is applied and validated for a hypothetical wind generation station and transported via submarine cables to the power network. The breaker was validated to a network voltage up to ±400 kV bipolar system and a rated power up to 360 MW. In the suggested breaker, two series of IGBTs were used. This breaker proof that it has a fast disconnecting capability, reliable and efficiency. A resistance–capacitance freewheeling diodes is used to suppress the overvoltage during the period of fault. The efficiency of the proposed breaker is proofed by a comparison its performance of the two different SSCB topologies. The comparison was established on the surge-voltage, the over-current suppression arising from short circuit current interruption and reconnection of semiconductor devices.
