Abstract: A high power-density power converter (500) employs a liquid cooling system (200) to cool its transformers (120). In an embodiment, the coils (135) of a transformer (100) are embedded in a heat-conducting solid (epoxy or resin). The resin-embedded coils (135) are in physical/thermal contact with cold plates (160), which are sandwiched between the coils (135) and/or in contact with exterior surfaces of the coils (135). The cold plates (160) may additionally or alternatively be in physical/thermal contact with the transformer core (145). Coolant fluid is pumped through the cold plates (160). In another embodiment, the transformer is (120) is immersed in a coolant fluid (740), such as oil, within a heat management enclosure (710). Cold plates (160) are in physical/thermal contact with the enclosure (710). Coolant liquid (240) pumped through the cold plates (160) conducts heat away from the oil-enclosed transformer (700).
