New reconfiguration technique for ultracapacitor for exchange of energy at A faster rate

Abstract

This paper deals with the use of the maximum energy of ultracapacitor at a faster transaction rate. This paperalso deals with the system-modeling, controller design, and faster energy transaction from ultracapacitor bank used in a hybrid electric vehicle. The energy transaction to dynamic load is through parallel-connected ultracapacitor bank and battery combination. The parallel-series topology has been implementing for ultracapacitor and the controller is designed to control energy-transactions from ultracapacitors. The DC-DC converter is only used for voltage regulation. This topology has aimed at the design leading to the excellent energy economy. Further, the main objective is to attain maximum utilization of energy in ultracapacitors during a ride-through condition, in minimum time. Three simulations have been carrying out with hardware implementation to compare these results. This includes energy sharing by ultracapacitor, in case of dynamic load. Hence, the proposed control strategy can provide a satisfactory improvement in energy-efficiency of ultra-capacitors, assuring maximum utilization and faster energy transaction.
