Abstract :
In this paper, a planar inductor based snubber circuit is presented for power MOSFET devices used in a Boost power converters. The proposed snubber can control the EMI effects caused by the switching actions which can affect the drive circuit. Appropriate use of the snubber and considering the parasitic elements in the switching circuits can improve the conducted EMI of the converter, eliminating the need for the bulky EMI filters. To design an effective snubber circuit, a physics based model of the switch and the snubber circuit components are considered. Using impedance control method, the effects of various parasitic elements that can cause the common-mode noise can be controlled. This effort enables the evaluation of interference issues for EMC evaluation studies early in the design process. The numerical results were validated experimentally.
