This thesis proposes a new passive soft-switching structure of interleaving buck converter (IBC), which has the following merits: (1) only needs a single capacitor to achieve the features of soft-switching and energy recycling, (2) decreases the difficulty of snubber design, and (3) efficiently lowers the implementation cost to meet the requirement of mass-production.
In this thesis, a detailed interpretation about the principles and designs of the proposed circuit structure is presented. By means of circuit simulation and practical manipulation, a 240 W IBC is implemented, from which voltage and current waveforms are measured to verify the theoretical discussion and feasibility. In addition, a characteristic comparison is made among the proposed circuit structure, hard-switching structure and two-set soft-switching structure. Furthermore, appropriate application fields of the three circuit structures are also presented.
