Abstract:
1. A power converter, comprising: a first circuit having an input adapted to receive an input power and convert the input power to an output power provided to an output; a housing encompassing the first circuit and having a thermally conductive member disposed proximate a portion of the first circuit, such that the first circuit is located in a first cavity defined by the thermally conductive member; and a second circuit configured to receive the input power and comprising a first emitter having a cathode and an anode, wherein the cathode and the anode are located in a second cavity which is opposite the first cavity, wherein the second circuit is adapted to create substantially directed ambient air flow across the thermally conductive member without using any moving parts, wherein the ambient air enhances cooling the power converter, wherein the substantially directed ambient air flow is substantially directed parallel to the thermally conductive member, and wherein the air flow is substantially contained within the second cavity.
