A wireless charging pad includes a rectifier, a receiver coil, a heat spreader plate sandwich between the rectifier and the receiver coil, and a ferrite cold plate sandwiched between the receiver coil and the heat spreader plate. The ferrite cold plate has a fluid inlet, a fluid outlet, and a fluid chamber in fluid communication with the fluid inlet and the fluid outlet. The fluid chamber includes a primary cooling chamber and a secondary cooling chamber. Primary cooling fins extending from the heat spreader plate are disposed in the primary cooling chamber and secondary cooling fins extending from a base of the ferrite cooling plate are disposed in the secondary cooling chamber. The ferrite cooling plate cools the rectifier and inhibits or blocks electromagnetic leakage from the receiver coil from interfering with operation of rectifier.
