电动玻璃升降器过流保护分析及措施

Analysis and Measures to Overcurrent Protection of Power Window Lifter

在对汽车电动玻璃升降器过流保护问题的分析过程中,提出一种基于PPTC器件的过流保护措施,并在某车型的电动玻璃升降器上进行了PPTC器件过流保护措施的实施、测试和验证,其失效故障得到了有效解决。

In the analysis of overcurrent protection of power window lifter, a protection measure based on the PPTC device is proposed and tested in a model of electric window lifter, which has solved the failure problem.
