Abstract
Systems for method for a semiconductor-based DC transfer switch. The semiconductor-based DC transfer switch uses two individual circuit breakers that are mechanically interlocked in such a way that only one of the two circuit breakers can be closed at any time. An actuator, such as a motor, operates mechanical arms that interact with the handles of the circuit breakers. At least one of the circuit breakers is a semiconductor-based DC circuit breaker.
Claims5
A transfer switch for bi-directional DC current flow, the transfer switch comprising:
- a first semiconductor-based DC circuit breaker configured to allow power flow from an input power source to an output power load, the first semiconductor-based DC circuit breaker including a first handle configured to open and close the first semiconductor-based DC circuit breaker;
- a second semiconductor-based DC circuit breaker configured to allow power flow from the output power load to the input power source, the second semiconductor-based DC circuit breaker including a second handle configured to open and close the second semiconductor-based DC circuit breaker;
- and
- an actuator configured to operate mechanical arms that interact with the first handle and the second handle such that the first semiconductor-based DC circuit breaker and the second semiconductor-based DC circuit breaker are mechanically interlocked, the mechanical interlocking of the first semiconductor-based DC circuit breaker and the second semiconductor-based DC circuit breaker being configured such that only one semiconductor-based DC circuit breaker of the first semiconductor-based DC circuit breaker and the second semiconductor-based DC circuit breaker is closed at any time.
