In order to be able to supply the 12V system and other consumers with electrical energy whose supply voltage is below the voltage of the respective HV system, a DC-DC step-down or buck converter is required. This function is integrated into the inverter and supplies, for example, the HV air conditioning compressor or charges the 12V battery.
