IMMERSION COOLED CAPACITOR FOR POWER ELECTRONICS CONVERTOR

摘要

A power electronics convertor is disclosed which includes a hermetically sealed housing, a dielectric cooling fluid contained in the housing, and a bank of capacitive elements disposed within the housing and submerged in the cooling fluid, wherein each capacitive element is wound about a hollow aluminum core forming an open interior region within the center of the capacitive element that is dimensioned and configured to optimize heat transfer between the capacitive element and the cooling fluid and reduce thermal stress in the capacitor.
