Abstract：

A　residual　current　protector　suitable　for　electric　vehicle　charging　mode　2　is　introduced　in　this　paper,　which　can　detect　the　sinusoidal　AC,　pulsating　DC,　smooth　DC　and　other　residual　current　waveforms　generated　during　electric　vehicle　charging.　The　magnetic　modulated　current　transformer　in　the　protector　is　used　to　detect　the　complex　residual　current,　the　low　pass　analog　filter　is　used　to　demodulate　the　signal,　and　the　residual　current　is　collected　and　analyzed　by　the　MCU.　Through　the　test,　the　protector　meets　the　leakage　protection　requirements　of　IEC62752　In-Cable　Control　and　Protection　Device　for　mode　2　charging　of　electric　road　vehicles,　IC-CPD.　Furthermore,　the　protector　characterizes　a　simple　structure,　small　size　and　low　cost.　©　2021　IEEE.
