  • ON-BOARD CHARGER SYSTEM WITH INTEGRATED AUXILIARY POWER SUPPLY
    Publication number: 20240178691
    Abstract: A charger including a charging interface and a converter coupled to the charging interface. The converter includes a first plurality of switching transistors coupled to the charging interface and a transformer including a primary winding, a secondary winding, and an auxiliary winding. The primary winding is coupled to the first plurality of switching transistors. A second plurality of switching transistors is coupled between the secondary winding and a battery interface. An auxiliary system interface is coupled to the auxiliary winding. A controller is configured to control the first plurality of switching transistors and the second plurality of switching transistors to generate a first signal at the battery interface and a second signal at the auxiliary system interface.
    Type: Application
