Abstract

A low voltage electromagnetic interference (EMI) filter of an electric vehicle is provided. In the low voltage EMI filter, a pair of Y capacitor units are respectively installed in input and output ends of the low voltage EMI filter. A normal mode (DM) filter and a common mode (CM) filter are installed between the pair of Y capacitor units. The pair of Y capacitor units, the DM and CM filters discharge CM and DM noises generated in a low voltage battery connection unit to a sash GND (earth) step by step and reduce noises of the low voltage battery connection unit.
