摘　　要：电源反接保护是汽车控制器电源电路的基本要求之一。本文以某车型电动助力转向控制器为例,根据该控制器工作电压和工作电流设计了3种汽车控制器电源反接保护电路,通过直流电子负载加载实验证明了3种电路的可行性。并根据实验曲线指出了所设计的3种电路应用范围。Reverse power supply protection is one of the basic requirements of automobile controllerpower supply circuit. Taking a vehicle EPS controller as an example, according to the controller work-ing voltage and current, three kinds of reverse power supply protection circuits of automobile controllerwere designed. The feasibility of three kinds of circuit was proved by DC electronic load experiments.According to the experiment curves, application range of three designed circuits was pointed out.
