摘　　要：针对动力电池组的三段式充电及其内阻极小特性,提出对三相电流型脉宽调制(PWM)充电机采用正弦脉宽调制(SPWM)间接电流控制策略以提高其功率因数,构建以TMS320F2808芯片控制的电流型PWM充电机控制系统样机并利用Matlab内Target Support Package软件包快速生成系统驱动代码。测试结果表明,充电系统具有较高的网侧功率因数和较好的输出电流波形,验证了SPWM间接电流控制策略的合理性及系统构建方案的有效性。Aiming at the characters of low internal resistance and three-stage charging mode of power batterygroups,the indirect current control strategy with sine pulse-width modulation（SPWM） was employed to promote thepower factor of current mode PWM charger, the sample of which is structured with the help of TMS320F2808 chip,and the target support package in Matlab was used to rapidly generate the drive code for this system. The test resultsindicate that the proposed scheme in this paper obtains higher power factor and better current waveform to validatethe reasonable SPWM indirect current control strategy and valid achieved system scheme.
