Résumé

The target application of the Hybrid Circuit Breaker presented in this paper is a 6.6 kV/60 Hz network for an electric ship. This Hybrid Circuit Breaker is based on a series association of IGCTs (Integrated Gate Commutated Thyristors) and a fast mechanical switch. In this new topology, thanks to the IGCT turn off control, the fault current is strongly limited and the mechanical switch, turned off at zero current, provides the voltage sustaining. To validate the principle of this Hybrid Circuit Breaker, the authors propose a test bench that can provide a 50 Hz sinusoidal short circuit current with a 18 kA-peak value and a maximum di/dt of 20kA/ms. This test bench displays interesting results and validates many key points of the new topology.
