DC/DC Converter
The purpose of the DC/DC converter is to function as an alternator in a conventional powertrain. The PCM controls operation of the DC/DC converter. Because the converter does not use any moving parts, the low voltage battery is charged when the vehicle drives with the engine ON or OFF. This is accomplished by converting power from the high voltage traction battery to a regulated output voltage of a nominal 14.5 volts, while supplying a load current of up to 110 amps. The PCM controls the DC/DC enable (DCE) hardwired signal to switch the DC/DC converter on and off. The DC/DC converter provides feedback to the PCM using the hardwired DC/DC fault (DCF) signal. The DCF signal indicates to the PCM when the converter is non-operation or when the malfunction occurred. The DC/DC converter is cooled by the motor electronics cooling system and is located on the passenger side in the engine compartment.
