| Abstract: | 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. |
