Abstract: An electrical circuit and a method for regulating current and providing a circuit breaker to the electrical circuit. The circuit includes a bidirectional cell including a set of forward switches for power flow during a forward mode of operation and a set of reverse switches for providing reverse power flow during a reverse mode of operation, a control inductor for controlling current flow during the reverse mode of operation, and a voltage clamping switch configured to provide the control inductor in the circuit during the reverse mode of operation and remove the control inductor from the circuit during the forward mode of operation. The circuit is operated in at least the reverse mode of operation.

Abstract: A regulated current-fed power system employs power branching units connected in series. Each power branching unit includes a plurality of parallel-redundant converter groups connected in series with each other within a current path for the regulated current. Each parallel-redundant converter group includes at least two direct current (DC)/DC converters connected in parallel with each other, each sharing the power load. A protection device connected in series with each DC/DC converter disconnects the respective DC/DC converter from the regulated current when the respective DC/DC converter short circuits, with the remaining DC/DC converter(s) then receiving more of the power load. An active clamp connected in parallel with all of the DC/DC converters within a parallel-redundant converter group temporarily sinks a portion of the regulated current when one of the DC/DC converters fails in a short-circuit condition. The active clamp shunts the regulated current around all DC/DC converters within the parallel-redundant converter group converters fail in a short-circuit condition.

Abstract: A solid-state zero current switching circuit breaker is configured to interrupt current flow between a voltage input and a load. The solid-state zero current switching circuit breaker includes at least one resonant capacitor cell having an input configured to receive a source voltage and an output configured to deliver drive current to the load. The resonant capacitor cell is configured to selectively limit the drive current to the output based on a variable voltage. The solid-state zero current switching circuit breaker further includes at least one voltage clamping switch configured to detect a short-circuit fault or an overload condition. The voltage clamping switch adjusts the variable voltage in response to detecting the short-circuit fault condition or the overload condition such that the resonant capacitor cell limits the drive current.
