In this paper, a novel soft switching power factor correction (PFC) interleaved AC-DC boost converter is proposed. In the proposed novel converter, all of the semiconductor devices operate with soft switching. The main switches turn on with zero voltage transition (ZVT) and turn off with zero current transition (ZCT) without any extra voltage or current stresses. Auxiliary switch turns on with zero...
This paper presents the research results of an optimized DC-DC voltage doubler based on a high-frequency resonant switched-capacitor (SC) topology. The converter utilizes a low weight PCB-type planar choke, and can be attractive for fuel cell-or battery-supplied systems which operate from low voltage where a voltage boost is needed. The optimization aims at minimizing power losses in the converter...
This paper is devoted to analyses of the boost converter using electrothermal average models. The modified forms of electrothermal average models of the diode — transistor switch and the inductor dedicated for SPICE are shown. The value of parameters of the considered models are estimated on the basis of the catalogue data for the considered converter components. The computations were performed for...
