PROBLEM TO BE SOLVED: To provide a protection system against reverse battery connection which is connected to a battery in an electric vehicle.SOLUTION: A protection system against reverse battery connection includes: a controller configured to output a first square wave signal including a third square wave signal and a fourth square wave signal to an input terminal of a transformer using a first DC voltage; the transformer configured to output a second square wave signal obtained by transforming the first square wave signal; a rectifier configured to rectify the second square wave signal to output a second DC voltage; and a transistor configured to perform protection against reverse connection of a battery using the second DC voltage.

    【課題】電気自動車内のバッテリと接続されるバッテリ逆接続保護システムを提供すること。【解決手段】本発明のバッテリ逆接続保護システムは、第1直流電圧を利用して、第3矩形波信号及び第4矩形波信号を含む第1矩形波信号を変圧器の入力端に出力する制御器と、前記第1矩形波信号を変圧させた第2矩形波信号を出力する変圧器と、前記第2矩形波信号を整流して、第2直流電圧を出力する整流器と、前記第2直流電圧を利用して、バッテリの逆接続を保護するトランジスタとを備える。【選択図】図2
