An expatiation to analyze and verification for zero-voltage-switching (ZVS) is proposed for cell voltage equalization control in a series connected super capacitors string. Resonant circuit was designed to achieve the ZVS to reduce the switching loss in equalization circuit. Analyze result indicates that the switching loss and equalization efficiency can be improved with the ZVS technology. The simulation and experimental results shows the ZVS equalization technology can achieve voltage equalization performance and reduce MOSFET switches power loss and increase the efficiency by 20% compared with the traditional equalizer.

Low Cost Embedded Controlled Full Bridge LC Parallel Resonant ConverterIn this paper the converter requirements for an optimum control of an electrolyser linked with a DC bus are analyzed and discussed. An electrolyser is a part of renewable energy system which generates hydrogen from water electrolysis. The hydrogen generating device is part of a complex system constituted by a supplying photovoltaic plant, the grid and a fuel cell battery. The characterization in several operative conditions of an actual industrial electrolyser is carried out in order to design and optimize the DC/DC converter. A dedicated zero voltage switching DC/DC converter is presented and simulated inside the context of the distributed energy production and storage system. The proposed supplying converter gives a stable output voltage and high circuit efficiency in all the proposed simulated scenarios. The adopted DC/DC converter is realized in a full-bridge topology technique in order to achieve zero voltage switching for the power switches and to regulate the output voltage. This converter has advantages like high power density, low EMI and reduced switching stresses. The simulation results are verified with the experimental results.
