A zero-voltage-switching (ZVS) Zeta converter is proposed in this paper. Two separate inductors in the conventional Zeta converter are magnetically coupled in the proposed converter. The output diode is replaced with an active switch. Also, an auxiliary inductor is utilized. The ZVS operation of both main and auxiliary switches is achieved and the switching loss is significantly reduced. Moreover, the ripple component of the output inductor current is effectively removed and the output filter stage can be simplified. To verify the feasibility and performance of the proposed converter, an experimental prototype was built and tested.

A novel three-phase power-factor-correction (PFC) rectifier with zero-voltage-switching (ZVS) in six main switches and zero-current-switching (ZCS) in the auxiliary switch is proposed, analyzed, and experimentally verified. The main feature of the proposed auxiliary circuit is used to reduce the switching loss when the six main switches are turned on and the one auxiliary switch is turned off. In this paper, a detailed operating analysis of the proposed circuit is given. Modeling and analysis are verified by experimental results based on a three-phase 7 kW rectifier. The soft-switched PFC rectifier shows an improvement in efficiency of 2.25% compared to its hard-switched counterpart at 220 V under full load.

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.
