DC/DC Converter
The DC/DC converter is a liquid-cooled component that converts high-voltage DC power to
low-voltage DC power. It maintains an electrical isolation between the 2 DC power systems. This
system converts the high voltage (275 volts) to low voltage (12 volts) that provides power to the
vehicle low-voltage battery systems. The PCM controls the operation of the DC/DC converter
through an enabled input from the PCM to the DC/DC converter.
