Document Type and Number:
WIPO Patent Application WO/2023/198070
Kind Code:
A1
Abstract:
Disclosed are an anti-reverse-flow control circuit for an in-vehicle redundant power source, and a vehicle controller and a vehicle. The circuit comprises a path switching module, a first anti-reverse-flow module and a second anti-reverse-flow module, wherein a first input end of the path switching module is connected to a first power supply source, a second input end thereof is connected to a second power supply source, a first output end thereof is connected to a control end of the first anti-reverse-flow module, and a second output end thereof is connected to a control end of the second anti-reverse-flow module; and an input end of the first anti-reverse-flow module is connected to the first power supply source, an input end of the second anti-reverse-flow module is connected to the second power supply source, and both an output end of the first anti-reverse-flow module and an output end of the second anti-reverse-flow module are connected to an electric load. On the basis of voltage values transmitted by the first power supply source and the second power supply source, the path switching module controls either the first anti-reverse-flow module or the second anti-reverse-flow module to turn on, and when being not turned on, the first anti-reverse-flow module and the second anti-reverse-flow module block the transmission of a current from an output end to an input end.
