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.
Claims19
An electric circuit, comprising:
- 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.
A method of regulating current and providing a circuit breaker to a circuit, the method comprising:
- forming an electric circuit between a first input voltage rail and a second input voltage rail, the electrical circuit including:
- 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 a reverse mode of operation, and
- a voltage clamping switch that is active during a reverse mode of operation to include the control inductor in the circuit and inactive during a forward mode of operation to remove the control inductor from the circuit;
- and
- operating the circuit in at least the reverse mode of operation.
