The invention relates to the field of motor controllers, in particular to a motor controller auxiliary power supply safety output circuit, which is characterized in that an output control unit is arranged between an auxiliary power supply and an output unit, the output unit is connected with a vehicle-mounted driving power supply, and auxiliary power supply voltage is output through the output unit; when the input end of the vehicle-mounted driving power supply is short-circuited, short-circuited or under-voltage, the output control unit controls the output state of the voltage of the auxiliary power supply according to the signal judgment unit, logicality is good, energy waste caused by the fact that the auxiliary power supply is in a power supply state all the time is avoided, and meanwhile the output unit carries out reverse protection on the voltage of the auxiliary power supply. And the safety is high. The problems of poor logic control and low reliability of the auxiliary power supply are solved.
本发明涉及电机控制器领域,具体涉及一种电机控制器辅助电源安全输出电路,在辅助电源与输出单元之间设置输出控制单元,并将输出单元与车载驱动电源连接,通过输出单元输出辅助电源电压,当车载驱动电源的输入端出现短路、短路或欠压问题时,输出控制单元根据信号判断单元俩控制辅助电源电压的输出状态,逻辑性良好,避免辅助电源一直处于供电状态而造成能源浪费,同时输出单元对辅助电源电压进行防反保护,安全性高。解决辅助电源逻辑控制差、可靠性低的问题。
