  • Publication number: 20240128849
    Abstract: A system comprises: a high voltage (HV) direct current (DC) to DC converter (HVDC) including: one or more transformers; a bridge driver connected to a primary side of the one or more transformers; and one or more bridge rectifiers connected to a secondary side of the one or more transformers, the one or more bridge rectifiers including one or more bridge rectifier switches; a low voltage (LV) DC to DC converter (LVDC) connected to the HVDC; and a boost converter including: an inductor connected to the one or more bridge rectifier switches; and one or more boost configuration switches operable, in combination with the one or more bridge rectifier switches, to configure the boost converter into each of a bypass configuration and a boost configuration, to regulate a voltage at the LVDC.

  • Publication number: 20240039413
    Abstract: A system for a direct current (DC)-DC converter includes a transformer, a bridge driver connected to a primary side of the transformer, and a bridge rectifier connected to a secondary side of the transformer, wherein one or more switches in the bridge driver are operable to configure the bridge driver into each of a half-bridge driver configuration and a full-bridge driver configuration, and to transition between the half-bridge driver configuration and the full-bridge driver configuration while the DC-DC converter is outputting power.
