An inverter power module cooling system for an electrified vehicle includes an inlet coupled to channels providing coolant from a heat exchanger in parallel to a plurality of power modules along a first edge of associated chips having one or more switches, and channels collecting coolant from a second edge of associated chips. An additional serpentine channel receives coolant from the inlet to cool an associated area of a thermally conductive capacitor pad. The system may include a base plate having channels on one side and providing coolant to one side of the power modules and the capacitor pad, and a channel plate secured to an opposite side of the base plate to provide coolant to an opposite of the power modules. Cover plates may be provided to seal the channels of the base plate and channel plate, or may be integrally formed by molding or additive manufacturing.
