汽车起动机保护电路的设计

Design of the Automobile Starter Protection Circuit

起动机是汽车启动系统的一个不可或缺的设备,一旦起动机出现故障会导致车辆不好启动,甚至有时无法着车。尤其是某些故障会导致起动机长时间工作,引起起动机烧蚀产生明火损坏线束和部分零件,因此对起动机的线路进行保护尤为必要。从起动机的工作原理进行分析,并尝试性地设计一个简易的起动机保护电路。

The starter is an indispensable equipment for automobile starting system,once the starter failure will cause the vehicle to a bad start,and sometimes even not a car. Especially some failures will cause the starter working for a long time,caused by the damage of the wire harness and fire starter ablating parts,so the starter line protection is necessary. From the analysis of the working principle of the starter,and try to design a simple starter protection circuit.
