Design and Control of Electric Power Train by Using Advanced Power Electronics Interface

A new integrated power electronics interface (IPEI) for battery electric vehicles (BEVs) in order to optimize the performance of the power train is proposed in this paper. As Power electronics interfaces plays important role in the automotive vehicle technologies the proposed IPEI is responsible for the power-flow management for each operating mode. The operating modes will explain how IPEI works during different modes like charging/discharging and traction/breaking modes. In this concept, an IPEI is proposed and designed to realize the integration of the dc/dc converter, on-board battery charger, and dc/ac inverter together in the BEV power train with high performance. The proposed concept improves the system efficiency and reliability, and reduces the current, voltage ripples, and also reduces the size of the passive and active components in the BEV drive trains compared to other topologies. And control strategy for IPEI is designed and analyzed by using MATLAB/Simulink. The simulation results related to the output waveforms are obtained and validated.
