Abstract
Methods and systems for a dielectric material coated busbar are provided. In one example, a conductive material may be formed into a shape of a busbar and portions of the busbar may be selectively coated with a dielectric material which may be both electrically insulating and thermally conductive. The dielectric coated portions of the busbar may dissipate heat to a heat sink via a thermal interface material compressed on the busbar.
Claims12
A method for a high voltage busbar, the method comprising:
- forming a conductor into a shape of the busbar;
- coating unmasked areas of the busbar with a thermally conductive dielectric powder material to form a dielectric coated portion of the busbar;
- and
- compressing the thermally conductive dielectric coated portion of the busbar to a thermal interface material (TIM) attached to a heat sink, the heat sink having a thickness greater than the TIM, wherein the TIM is only in direct contact with the thermally conductive dielectric coated portion of the busbar and the heat sink.
