An integrated electronic power control unit of an environmentally friendly vehicle includes an inverter and an LDC (low voltage DC-DC converter), which share a DC input terminal. In the integrated electronic power control unit, the inverter is an electronic power control unit that drives a motor by converting DC voltage into AC voltage, and the low voltage DC-DC converter serves as another electronic power control unit that charges a low-voltage battery by converting DC high voltage into low voltage DC voltage, where the inverter includes a capacitor module composed of a capacitor leveling input voltage and a capacitor removing noise of the input voltage, and the inverter and the low voltage DC-DC converter are integrated such that the output of the capacitor module of the inverter becomes the output of the low voltage DC-DC converter.
