Mixed Energy Transfer (MET) Innovative Structure based on LCT and comparison with traditional structures

In power electronics, design of power supply is always tending to miniaturization. Passive components represent the main part of the volume. Integrating these elements is a major keypoint to reach a high level of reduction. In order to achieve this, different works have already begun in the world (Chen, 2003). In this paper, we present research on volumes of passive components reduction, inductor-transformer-capacitor. This is fundamental for the miniaturization of all structures of power electronics. One way to achieve this goal is to combine these three passive elements in only one passive component called LCT. We see how physical limits of this association are constrained by the possible capacitor value considering the dielectric performances. In a second part, a new topology of converter called mixed energy transfer (MET) structure adapted to the LCT is introduced; it can offer industrial interests in a near future. This topology is compared with more classic ones to demonstrate its advantages
