The invention provides an actuator, a power supply method and a power supply system. The actuator comprises a power input end, a power supply enabling end, a power supply control unit, a discharge unit, an energy storage unit and a control unit. The power supply control unit is electrically connected with the power supply input end, the power supply enabling end, the control end of the discharge unit, the connection node and the grounding end, the power supply input end inputs power supply voltage, the power supply enabling end inputs power supply enabling signals, and the power supply control unit controls the access state between the power supply input end and the power supply end of the control unit based on the power supply enabling signals. When the power supply enable signal is effective, a first conduction level signal is provided for the control end of the discharge unit, and the discharge unit conducts the access between the connection node and the grounding end to discharge the electric energy stored in the energy storage unit, so that after the controller stops supplying power to the actuator, the voltage of the high-side power supply output end is smaller than a threshold value in the diagnosis window, and the voltage of the high-side power supply output end is smaller than the threshold value in the diagnosis window. And the probability of misjudgment when the controller diagnoses the high-side power supply output end is reduced.

    本申请提供一种执行器、供电方法及供电系统,执行器包括电源输入端、供电使能端、供电控制单元、泄放单元、储能单元和控制单元;供电控制单元与电源输入端、供电使能端、泄放单元的控制端、连接节点以及接地端电连接,电源输入端输入供电电压,供电使能端输入供电使能信号,供电控制单元基于供电使能信号控制电源输入端与控制单元的供电端之间的通路状态,当供电使能信号有效时,向泄放单元的控制端提供第一导通电平信号,泄放单元导通连接节点和接地端之间的通路,以泄放储能单元中存储的电能,从而控制器在停止为执行器供电后,使高边供电输出端的电压在诊断窗口内小于阈值,降低控制器对高边供电输出端诊断时的误判断的概率。
