Abstract
A fluid-cooled magnetic component. The coil is formed with small gaps between the turns of the coil. A coolant flows through these gaps, thereby cooling the coil. Multiple coil paths for core cooling and a separate path for winding cooling are provided. One coil path is formed by the annular gap between the inner diameter portion of each coil and the core, and a second cooling path is located between the radial gaps between each coil.
