Reduction of heat sink common-mode currents in switching mode power supply circuits

[摘要] In this paper, a new filter design for a heat sink is presented. Theparasitic couplings between electric power devices and the heat sink areresponsible for common-mode currents. The main focus is on the reduction ofthese currents to reduce the heat sink radiation. For this purpose a newfilter design is proposed. In addition, experimental results are shown tovalidate the proposed filter.
