An extensive power balance management of hybrid electrical vehicles fast charging stations architecture using NPC converter

Abstract

As there is a high growth in number of hybrid vehicles day by day there is more need to decrease the time to charge, so that there is a need of development of high power charging stations with quick charging is needed so that we can reduce the excitement of drivers. The charging stations based on neutral point converter(NPC) have many advantages but it has an unbalanced problem in the bipolar dc bus. To solve this unbalanced problem in the dc bus An extensive power balance management system with the help of space vector modulation technique is proposed in this paper. This power balance management(PBM) is proposed to support the central neutral point clamped converter(NPC) in balancing the power and to maintain the fluctuating neutral point current zero and to make sure the balanced operation of fast chargers so that the dc bus is maintained constant and balanced. The overall architecture and the effective integration of solar, wind and fast charger connected to NPC converter is proposed. Simulation results are presented and results are verified in the paper.
