This paper presents a two-stage DC/DC converter with high efficiency utilized in an electronic power conditioner (EPC), which is widely applicable satellite communications, etc. The galvanically isolated contains two cascaded converters: buck converter, pre-regulator operating under closed-loop condition, and push–pull intended to boost the input voltage, open-loop condition. In switches, inclu...
A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...
In this paper, a DC–DC converter topology with a zero voltage and zero current switching control technique [8] has been proposed for solar PV applications. The proposed converter combine the feature of buck–boost operation capability, at the same time, it can carry out zero voltage and zero current switching on the primary side of the converter transformer. The proposed work has been carried ou...
Recently, the LLC resonant converter has drawn a lot of attention due to its advantages over the conventional series resonant converter and parallel resonant converter: narrow frequency variation over wide load and input variation and Zero Voltage Switching (ZVS) of the switches for entire load range. This paper presents an analysis and reviews practical design considerations for the LLC-type r...
