Application analysis of leakage protection in electric vehicle charging pile
Jul 25 , 2022
As the world's largest consumer of new energy electric vehicles, new energy electric vehicles are developing rapidly, and the safety of electric vehicle charging piles is a top priority: whether the electric vehicle charging pile can avoid random plugging and unplugging during the charging process. The accident caused by the charging gun, whether it can be automatically powered off after charging,...

Leakage current generation classification
Jul 25 , 2022
Generally, there are four types of leakage currents: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current 1. Leakage current of semiconductor components The very small current that flows through the PN junction when it is turned off. D-S is forward biased, G-S is reverse biased, and after the conductive channel is opened, curre...
