| 摘 要： | 针对脉宽调制(PWM)逆变器，在研究逆变电源电压矢量的基础上，将空间矢量脉宽调制(SVPWM)技术应用于三相和单相PWM逆变电源，分别给出了三相和单相SVPWM的数字信号处理(DSP)算法，给出了一种开关模式优化的单相SVPWM算法，导出了三相和单相SVPWM基于载波调制的调制波形式以及零序信号形式，指出载波零序信号在本质上对应着逆变器零电压矢量作用时间分配与分布，论证了SVPWM与载波PWM的统一，实验结果验证了SVPWM算法的有效性.

| Abstract: | For the control of Pulse Width Modulation(PWM) inverter,the Space-Vector PWM(SVPWM) technique was been applied to three-phase inverter and single-phase inverter based on the inverter voltage space vector analysis.Then,the realization method based on Digital Signal Processing(DSP) for three-phase and single-phase SVPWM technique was described in detail.An optimal switching SVPWM technique was given.The three-phase SVPWM carrier-based modulation form and its zero-sequence signal has been deduced.Through the p... |
