摘要
建立了三电平整流器数学模型,采取电压定向的直接电流控制,并使用新型的电压空间矢量脉宽调制(SVP-WM)算法减少计算量,简化了中点电位控制策略。最后建立了基于TMS320F2812型DSP的三电平整流器平台,实验结果验证了算法的有效性。
The mathemalical model of three-level rectifier is introduced.Besides,the voltage-oriented control including direct current control is used,a novel simplified space-vector pulse width modulation is applied to reduces calculation and to simplifies the neutral-point potential control strategy.A three-level rectifier platform based on DSP TMS320F2812 is built up for this research.The validity of the control strategies is demonstrated by the experimental results.
