Reduction of heat sink common-mode currents in switching mode power supply circuits
Helmut-Schmidt-University/University of the Federal Armed Forces Hamburg, Germany
Abstract. In this paper, a new filter design for a heat sink is presented. The parasitic couplings between electric power devices and the heat sink are responsible for common-mode currents. The main focus is on the reduction of these currents to reduce the heat sink radiation. For this purpose a new filter design is proposed. In addition, experimental results are shown to validate the proposed filter.
