DUAL-WAY ELECTRIC TRACTION DRIVE FOR AN ULTRACAPACITOR PACK

Abstract

A hybrid energy storage system made up of battery power unit as well as an ultra capacitor pack is recognized as. A parallel electricity-linked multi input ripper tools having a half-bridge bidirectional Electricity/Electricity cell topology is selected to link battery Or ultra capacitor storage space uses the electricity-link. The paper concentrates on modeling the suggested ripper tools for dynamic and steady condition analysis. This paper presents modeling, design and analysis of the bidirectional half-bridge Electricity/Electricity ripper tools appropriate for power electronic interface between your primary energy storage system and also the electric traction drive in hybrid electric vehicles. Averaging and linearization techniques are applied to get the averaged condition space models and small signal types of the ripper tools both in boost and buck operation modes. A qualifying criterion for sizing the ripper tools passive components in line with the enforced design specifications and constraints is highlighted. Particularly, short-circuit problems and open-circuit problems of diodes and transistors are examined. Simulation outcomes of the buck-boost ripper tools during normal functioning and under faulty the weather is presented.
