Vehicle Electric Drive In a power converter or motor drive, the power source is DC (or converted to DC). The DC link capacitor acts as a buffer between the power source and the inverter. A diagram of a typical hybrid vehicle is shown. Though the power source and output may vary, the same principle applies to wind turbines, solar converters and industrial drives.
