Abstract
A power supply circuit and an emergency device are provided. The power supply circuit includes a load interface for connecting a load; a power supply switch for connecting or disconnecting a circuit between an energy storage unit and the load interface; a main control circuit, configured to control the power supply switch to be in a state of connecting or disconnecting, so as to connect or disconnect a power supply path between the energy storage unit and the load. By utilizing the main control circuit, the control to the switch of power supply to load can be optimized.
Claims20
A power supply circuit, comprising:
- a load interface for connecting a load;
