This paper presents the concept and results of a novel resonant DC-DC converter which achieves high voltage gain at low number utilized switches, stress on transistors, ZVS ZCS operation, efficiency variable gain. The uses switched-capacitors (SC) circuits with five switches allows it to reach six-fold By application adequate switching patterns, seven levels adjustment can be achieved. basic op...

A full-bridge converter which employs a coupled inductor to achieve zero-voltage switching of the primary switches in the entire line and load range is described. Because the coupled inductor does not appear as a series inductance in the load current path, it does not cause a loss of duty cycle or severe voltage ringing across the output rectifier. The operation and performance of the proposed ...

With a development of Hybrid Electric Vehicle(HEV), A photovoltaic(PV) generation system is used for charging batteries in many cases. A dc/dc converter using PV power for a battery charger requires a high efficiency. In this paper, A ZVS boost converter using the renewable energies for HEV charger is proposed. Through the theoretical analysis and experimental result, operation modes and charac...

A novel single-stage AC/DC converter is proposed in this letter. The converter is designed by integrating a sepic circuit and a flyback circuit, the circuit work in the quasi-resonance state, and the switch is turned on in the zero voltage switching (ZVS) state, which decreased the switching losses of the converter Streszczenie. Opisano nowy konwerter AC/DC. Układ pracuje w stanie quasi-rezonan...

Triple active bridge (TAB) as an isolated multiport converter is a promising integrated energy system for smart grids or electric vehicles. This article aims to derive and analyze zero voltage switching (ZVS) regions of TAB, in which both losses are reduced, electromagnetic interference issues mitigated. In the proposed closed-form solution ZVS criteria, parameters such parasitic capacitance sw...

Generally, power electronic converters are designed to obtain the highest efficiency at rated while they most often operated under partial loading conditions. For dual active bridge converters, zero-voltage-switching (ZVS) conditions can be impaired light load situations. While depending ZVS operation has been introduced by prior-art approaches, nonlinear characteristic of output capacitance in...
