Abstract:
1. A fault tolerant synchronous rectifier PWM regulator system comprising: a force commutated synchronous rectifier comprising an intrinsic body diode, and operable to be coupled to an electrical bus and eliminate a reverse recovery time of the intrinsic body diode by forcing a commutating current across the intrinsic body diode: a low side switch operable to be coupled to a common ground; a first fuse coupled to the force commutated synchronous rectifier and the low side switch, and operable to open in response to a first fault whereby the electrical bus remains coupled to a current source; an inductor coupled to the first fuse, the force commutated synchronous rectifier, and the low side switch; a second fuse coupled to the inductor and operable to be coupled to the current source, and operable to open in response to a second fault whereby the electrical bus remains coupled to the current source; and a bypass rectifier coupled to the second fuse, and the force commutated synchronous rectifier, and operable to be coupled to the current source.
