Claim 8:
9. A method of cooling a power converter, the method comprising:
operating a power converter, wherein the power converter includes:
a plurality of printed circuit boards (PCB) connected via a plurality of connector rods, the plurality of PCBs including a lower-most PCB and an upper-most PCB;
a liquid cooling mechanism attached to the lower-most PCB;
high-loss circuitry components attached to the lower-most PCB;
low-loss circuitry components attached to one of the plurality of printed circuit boards, wherein the high-loss circuitry components have higher losses relative to the low-loss circuitry components;

actively cooling the high-loss circuitry components via the liquid cooling mechanism; and
passively cooling the low-loss circuitry components,
wherein the power converter further includes magnetic components attached to the upper-most PCB.
