A hybrid power control apparatus for a vehicle includes an inverter module disposed in a housing; a low DC-DC converter (LDC) module disposed in the housing; and a component mounting part attachably/detachably assembled in the housing. In the hybrid power control apparatus, the inverter module includes a plurality of power modules; a cooler contacts both surfaces of each power module so as to carry out heat conduction, the cooler assembled to the component mounting part; and a capacitor module assembled in a form where the capacitor module is stacked on one side of the cooler so as to carry out heat conduction. As a result of this structure, cooling efficiency can be improved, and the inverter module, the converter module, and a controller are packed in one closed space, thereby reducing the size of the hybrid power control apparatus.
