Abstract
An inductor includes an elongate magnetic core, a coil wrapped around the core and a spacer that separates the coil from the core to provide a coolant passage between the coil and the core. The coolant passage may include an air passage that extends substantially parallel to an axis of the core and that has first and second openings proximate respective first and second ends of the core. The coil may include a twisted bundle of individually insulated conductors. The inductor may be housed in a flux-tolerant compartment, i.e., a conductive aluminum structure that supports eddy currents with relatively acceptable resistive losses.
