Double star chopper cell converter for battery electric vehicles with inter-module SoC balancing and fault tolerant control
Kandasamy, Karthik, Vilathgamuwa, D. Mahinda, & Tseng, King-Jet (2014) Double star chopper cell converter for battery electric vehicles with inter-module SoC balancing and fault tolerant control. In Proceedings of the 40th Annual Conference of IEEE Industrial Electronics Society (IECON 2014), IEEE, Sheraton Hotel Dallas, Dallas, Texas, USA, pp. 2991-2996.
A modularized battery system with Double Star Chopper Cell (DSCC) based modular multilevel converter is proposed for a battery operated electric vehicle (EV). A design concept for the modularized battery micro-packs for DSCC is described. Multidimensional pulse width modulation (MD-PWM) with integrated inter-module SoC balancing and fault tolerant control is proposed and explained. The DSCC can be operated either as an inverter to drive the EV motor or as a synchronous rectifier connected to external three phase power supply equipment for charging the battery micro-packs. The methods of operation as inverter and synchronous rectifier with integrated inter-module SoC balancing and fault tolerant control are discussed. The proposed system operation as inverter and synchronous rectifier are verified through simulations and the results are presented.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
