Abstract:
In one aspect, a method is described. The method may include operating a plurality of circuit elements, and operating a plurality of fault-mitigation circuits. Each circuit element may include an energy storage element, each individual fault-mitigation circuit may be electrically coupled in parallel to a respective circuit element, and each individual fault-mitigation circuit may include a switch. The method may include detecting an electrical fault in one of the circuit elements and cycling the switch of the fault-mitigation circuit coupled in parallel to the faulty circuit element between an open position and a closed position until the storage element of the faulty circuit element is discharged of energy, at which point the switch remains closed.
