Abstract

Integration of power electromagnetic components, such as HF transformers, resonant/choke inductors and resonant/blocking capacitors, for switch mode power supplies (SMPS) has been studied in the past few years to reduce the count, volume and profile of the components so as to increase the power density of the converter. Its applications in resonant and nonresonant SMPS have been reported. However, very little work has been done on the subject of filter integration. To bridge this gap, the integration of an EMI filter for a DPS front-end converter is presented in this paper. The planar integrated L-C technology is used to integrate the filter components. The design issues of the integrated EMI filter are discussed and the experimental results are given.
