| Abstract |
In recent years, power electronic energy storage
systems using super capacitor bank have been widely
studied and developed for the electronic vehicles. In this
paper, a full-bridge/centertapped push-pull circuit-based
bidirectional DC-DC converter and its control method are
proposed and discussed. From the results of detailed
experimental demonstration, the proposed system is able to
perform adequate charging and discharging operation
between low-voltage high-current super capacitor side and
high-voltage low-current side with drive train and main
battery. Furthermore, conduction losses and voltage/current
surge are drastically reduced by ZVS operation with lossless
snubber capacitor in high-voltage side as well as the
synchronous rectification in low-voltage high-current super
capacitor side. |
