Title:
CIRCUIT SYSTEM, CONTROL METHOD OF CIRCUIT SYSTEM, CONTROLLER AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/077974
Kind Code:
A1
Abstract:
Provided are a circuit system, a control method of the circuit system, a controller and a non-transitory computer-readable storage medium, which relate to the technical field of electronic circuits. The circuit system comprises: a system power supply; a magnetic latching relay electrically connected to the system power supply; direct-current buses electrically connected to the magnetic latching relay; a direct-current bus capacitor arranged between the direct-current buses; and a controller electrically connected to the direct-current bus capacitor and configured to send, when the system power supply stops supplying power, a disconnection control pulse to the magnetic latching relay by using the electric energy stored by the direct-current bus capacitor. According to the present disclosure, when a system power supply stops supplying power, residual electricity stored in a direct-current bus capacitor is used to drive a magnetic latching relay to be kept disconnected, such that a voltage on the direct-current bus capacitor is rapidly discharged, thereby improving the safety of a circuit system.
