Abstract

By adding some switches to the traditional 24-pulse thyristor-based rectifier, this paper presents a new multi-pulse flexible-topology thyristor-based rectifier (mPFTTR) which has several operating modes, besides the conventional series and parallel modes. The new mPFTTR may be a suitable application in a single-stage battery charger of electric vehicles (EVs), which can work in five different modes: series mode with 24 pulses (SM24P), parallel mode with 24 pulse (PM24P), hybrid modes with 24 pulses (HM24P), series mode with 12 pulses (SM12P) and parallel mode with 12 pulses (PM12P). As fast charging seems especially important to a battery charger due to the continuously growth of EVs on the road, the paper also presents the predictive current control strategy combined with a multi-step constant current charging method to fulfill the fast-current response. Simulation verifications are carried out, and results show that this combined control strategy can adjust the charging current rapidly, which the fast charging is achieved.

一种适合多种工作模式的电动汽车电池充电器单级结构

本文通过在传统的24脉冲晶闸管整流器的基础上增加一些开关，提出了一种新的多脉冲柔性拓扑晶闸管整流器(mPFTTR)，该整流器除具有传统的串并联工作模式外，还具有多种工作模式。新型mPFTTR可能适合应用于电动汽车的单级电池充电器，它可以在五种不同的模式下工作:24脉冲串联模式(SM24P)、24脉冲并联模式(PM24P)、24脉冲混合模式(HM24P)、12脉冲串联模式(SM12P)和12脉冲并联模式(PM12P)。由于道路上电动汽车的不断增长，快速充电对电池充电器显得尤为重要，本文还提出了结合多步恒流充电方法的预测电流控制策略，以实现快速电流响应。仿真验证结果表明，该组合控制策略能够快速调节充电电流，实现了快速充电。
