A Novel Application of Zero-Current-Switching Quasiresonant Buck Converter for Battery Chargers
The main purpose of this paper is to develop a novel application of a resonant switch converter for battery chargers. A zero-current-switching ZCS converter with a quasiresonant converter QRC was used as the main structure. The proposed ZCS dc–dc battery charger has a straightforward structure, low cost, easy control, and high efficiency. The operating principles and design procedure of the pro...
متن کاملSimulation of a Zero-Voltage-Switching and Zero-Current-Switching Interleaved Boost And Buck Converter
A novel interleaved boost and buck converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristic is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing the common soft-switching module, ...
متن کاملSoft Switching Buck Converter for Battery Charging With MPPT
Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...
متن کاملA New Application of the Multi-Resonant Zero-Current Switching Buck Converter: Analysis and Simulation in a PMSG Based WECS
A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and contr...
متن کاملAnalysis, Design and Control of Zero Current Switching DC To DC Buck Converter
A soft-switching buck converter is proposed for battery charging application. This converter can also be used with other low voltage miniature applications. Resonant inductor and capacitor helps to turn on-off the switch at zero current. This reduces switching losses in our conventional converter. In order to determine two (current) zero-cross points for switch-on and switch-off, the quasi-reso...
