The invention relates to a reverse flow prevention control circuit of a vehicle-mounted redundant power supply, a vehicle controller and a vehicle. The circuit comprises a path switching module, a first reverse flow prevention module and a second reverse flow prevention module, the first input end of the access switching module is connected with the first power supply, the second input end is connected with the second power supply, the first output end is connected with the control end of the first anti-reverse module, and the second output end is connected with the control end of the second anti-reverse module; the input end of the first anti-reverse module is connected with a first power supply, the input end of the second anti-reverse module is connected with a second power supply, and the output end of the first anti-reverse module and the output end of the second anti-reverse module are both connected with an electricity load. The access switching module controls one of the first anti-reverse module and the second anti-reverse module to be switched on based on voltage values transmitted by the first power supply and the second power supply, and when the first anti-reverse module and the second anti-reverse module are not switched on, current is prevented from being transmitted from the output end to the input end; therefore, reverse irrigation prevention of the power supply is realized.
本公开涉及车载冗余电源的防反灌控制电路、车辆控制器及车辆,该电路包括:通路切换模块、第一防反模块和第二防反模块;通路切换模块的第一输入端连接第一供电电源,第二输入端连接第二供电电源,第一输出端连接第一防反模块的控制端,第二输出端连接第二防反模块的控制端;第一防反模块的输入端连接第一供电电源,第二防反模块的输入端连接第二供电电源,第一防反模块的输出端和第二防反模块的输出端均连接用电负载。通路切换模块基于第一供电电源和第二供电电源传输的电压值,控制第一防反模块和第二防反模块择一导通,第一防反模块和第二防反模块在未导通时阻断电流由输出端向输入端传输;如此,实现了供电电源的防反灌。
