Abstract

This paper presents a predictive control system for the front-end Buck-Boost rectifier of an electric vehicle fitted with an integrated battery charger. The drive of this electric vehicle is based on a dual inverter connected to the open-windings induction motor. The rectifier of the integrated charger is based on the high-power factor AC-DC current source converter presenting Buck-Boost characteristics. This converter allows an easy integration in the electric vehicle charger, as well as zero average torque during the charging process. However, existing control systems for this front-end Buck-Boost rectifier are complex and hard to tune. To automate the rectifier vector selection, this paper proposes the use of a model predictive controller (MPC) to control the three-phase charger rectifier AC currents and the voltages capacitors of the dual inverter. Several simulation tests of the AC currents MPC controlled show nearly sinusoidal input currents and near unity power factor operation.

双逆变驱动电动汽车集成电池充电器降压整流器模型预测控制器

提出了一种集成电池充电器的电动汽车前端Buck-Boost整流器预测控制系统。这款电动汽车的驱动是基于连接到开式绕组感应电机的双逆变器。集成充电器的整流器是基于具有Buck-Boost特性的高功率因数AC-DC电流源变换器。这种转换器可以很容易地集成在电动汽车充电器，以及零平均扭矩在充电过程中。然而，这种前端Buck-Boost整流器的现有控制系统是复杂的，难以调整。为了实现整流器矢量选择的自动化，本文提出了一种模型预测控制器(MPC)来控制三相充电器整流器的交流电流和双逆变器的电压电容。对MPC控制的交流电流进行了多次仿真试验，结果表明输入电流接近正弦，功率因数接近单位。
