Abstract: An apparatus includes: a power converter including a plurality of electronic switches, the electronic switches being controllable to produce a driver signal having a variable amplitude, frequency, and/or phase; and a single-piece base made of a thermally conductive polymer material. The single-piece base includes: a first side configured to hold the power converter; a second side; and one or more heat dissipating elements that extend from the second side. The heat dissipating elements are configured to dissipate heat generated by the electronic switches, and each of the one or more heat dissipating elements is made of the thermally conductive polymer material.

Abstract: An enclosure assembly includes a housing defining an interior configured to at least partially house one or more electrical components. The housing includes a housing section including an outer plastic portion and an inner metal portion received in the outer plastic portion.
