DC-DC Converter The DC-DC converter converts the main battery’s high voltage (200 to 400 volts) to the auxiliary battery’s lower voltage (12 volts) and charges the auxiliary battery. The DC-DC converter also serves as a power source for 12-volt equipment including headlamps, windshield wipers and horns. In 1997, DENSO started supplying the DC-DC converter for hybrid electric vehicles.
