Design of a New Electrical Model of Integrated LC Filter in DC-DC Converter

摘要

This paper presents a new structure of integrated low-pass LC filter in a converter DC-DC. This micro-filter consists of a planar circular coil placed between two Mn-Zn ferrite substrates. This ferrite is chosen because of its interesting electrical and magnetic characteristics. In this micro-filter the Mn-Zn ferrite substrate acts not only as a magnetic core, but also as a capacitor. The PSIM 9.0 software is used to validate the results of dimensioning as well as the operation of the integrated dimensional filter.
