1. A system comprising:
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 at the one or more bridge rectifiers; 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.
