| 摘 要： | 在研究多电平空间矢量脉宽调制(SVPWM)算法的基础上提出了一种与SVPWM算法等效的三电平载波调制(TCPWM)算法,并给出了统一的零序分量表达式。与SVPWM相比,该算法不仅在输出畸变率、直流电压利用率等指标上与SVPWM算法完全相同,且具有运算时间短、算法简单、易于实现等特点。最后将TCPWM算法运用在三电平整流器中,实验结果验证了TCPWM算法的可行性。

| Abstract: | Based on the reseach of three-level space vector pulse width modulation(SVPWM) algorithm,three-level carrier pulse wave modulation(TCPWM) algorithm which is equivalent to SVPWM is proposed.The uniform expression of zero sequence component is also proposed.The TCPWM algorithm is equivalent to SVPWM on distorted ratio of output voltage and operating factor of DC voltage,and can save the time of computation and can be easily computed or realized.Finally,TCPWM is used in the three-level rectifier,the experiments verify the feasibility of the TCPWM. |
