A Research of New Zero-Voltage Switching Equalization for Super-Capacitor Energy Storage System

Abstract:

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.
