Abstract
A method of operating an on-board charger for charging a high voltage battery of an electrically-charged vehicle includes supplying a DC voltage obtained by converting an AC voltage to the high voltage battery to perform a charging operation, measuring an internal voltage of a DC EMI filter for removing noise of the DC voltage, generating a leakage current estimate based on the internal voltage, and controlling the charging operation in accordance with the leakage current estimate.
