Electromagnetic DC pulse power system including integrated fault limiter

摘要

An electromagnetic direct current (DC) power system includes a plurality of pulse forming networks (PFN) modules. Each pulse forming network (PFN) module includes a PFN circuit, a fault current limiting (FCL) circuit and a cooling system. The pulse PFN circuit is configured to generate a pulsed DC output power. The PFN circuit further includes at least one energy storage inductor with primary winding having a primary winding inductance that controls a primary impedance of the PFN circuit. The FCL circuit includes a secondary winding that electrically communicates with the primary winding. The FCL circuit is configured to receive fault energy existing in the PFN circuit during a fault event. The cooling system is configured to cool at least one of the primary winding and the secondary winding, and remove a portion of the fault energy.
