Solid state circuit breaker with physical switch and electronic control
A recently granted patent (Publication Number: US11973335B1) discloses a circuit breaker that combines an electro-mechanical switch with a solid-state circuit breaker to enhance safety and efficiency. The circuit breaker includes an electro-mechanical switch with a physical switch that moves between open and closed positions, along with an actuator for controlling the switch. A solid-state circuit breaker is also integrated, featuring a coupled transistor pair, a sensing circuit, and a controller circuit. The sensing circuit is designed to detect fault conditions and trigger the solid-state circuit breaker to turn off the transistor pair independently of the controller, providing redundancy for enhanced reliability.
Furthermore, the solid-state circuit breaker includes a current limiting circuit activated by a trip signal, a driver circuit, and additional components for efficient operation. The controller circuit plays a crucial role in monitoring and responding to fault conditions, generating trip signals, and coordinating the actions of the various circuit components. The integration of both electro-mechanical and solid-state elements in the circuit breaker ensures a comprehensive approach to current flow interruption in response to potential faults, enhancing overall safety and performance.
