| 摘 要： | 通过对三相SVPWM思想、方法与研究手段进行类比,将SVPWM技术推广至单相PWM逆变电源.针对单相逆变电源的特点,引入单相"线电压"概念,并在此基础上分析了单相空问电压矢量,提出了单相电压矢量空间的坐标旋转变换方法.详细介绍了单相SVPWM算法的实现方法,给出了一种开关优化的单相SVPWM算法.最后通过构建实验平台,用实验验证了文中所述单相SVPWM逆变控制算法.

| Abstract: | Through analogising the analysing of three-phase PWM inverter,the Space-Vector PWM technique is applied to S.P.inverter.A line-line voltage concept for S.P.inverter is introduced.Based on this,the voltage space vector for S.P.inverter is analysed and a plane coordinate rotating transform method is brought forward.The realization method for S.P.SVPWM technique is described in detail.A doubled harmonic frequence property is shown,a optimal switching SVPWM technique is brought forward.Finally,the experiment is... |
