  • Publication number: 20200170141
    Abstract: A method is provided for heat dissipation in a current compensation circuit (211, 221, 231) of a charger that charges a high-voltage battery. The charger is supplied with AC current from a charging cable on its input side and DC current for charging the high-voltage battery is provided by the charger on its output side. The charger does not have galvanic isolation and a leakage current is brought about by the AC current in at least one capacitor that is installed in the charger on the input side and connected to a protective conductor. The leakage current is compensated by the current compensation circuit (211, 221, 231) that is formed by power semiconductor electronics (211, 221, 231). Heat arising in the power semiconductor electronics (211, 221, 231) is dissipated by connecting the power semiconductor electronics to a carrier plate (212, 222, 232) within a housing of the charger (100).
