LEAKAGE CURRENT CANCELLATION DEVICE AND VEHICLE SYSTEM INCLUDING THE SAME

Disclosed is a leakage current cancellation device. The device includes a leakage detection resistor connected between a first node connected to a vehicle body ground of a vehicle and a second node connected to a second ground of an external power source. The devices further includes a voltage follower connected in parallel with the leakage detection resistor between the first and second nodes. The voltage follower cancels a potential difference between the first and second nodes.
