Abstract
An improved choke assembly for a power electronics device is provided. More specifically, a choke assembly with improved protection from environmental conditions such as dirt and water is provided. An improved choke assembly may include a double layer of protection around an inductor coil of a choke that seals the inductor coil from the outside environment. Another embodiment may include a choke with a projection that seals the cabinet from the cooling channel while allowing the choke leads to pass into the cabinet.
