摘要
为了将空间矢量脉宽调制(SVPWM)技术应用于单相逆变电源,在研究分析三相逆变电源SVPWM技术原理基础上,引入单相电源的电压状态矢量空间和平面坐标旋转变换;通过单相PWM逆变电源电压状态矢量空间分析,提出一种单相SVPWM技术,并给出了实现方法。实验验证了单相SVPWM逆变控制算法的有效性,结果表明SVPWM技术不仅适用于单相PWM逆变电源,而且由三相SVPWM技术中研究所得的各类优化PWM技术亦可应用于单相逆变电源。
To apply the space-vector PWM (SVPWM) technique to the single-phase PWM inverter,in this paper firstly analyzed the basic principle of three-phase VPWM technique. Based on the analysis of the three-phase SVPWM technique. A single-phase voltage vector space and a plane coordinate rotating transform were introduced. Then,a single-phase SVPWM technique and its realization method were put forward. Finally,the validity of single-phase SVPWM technique was proved from the experiment. And the result proved that not only the SVPWM inverter control algorthm can be applied to single-phase PWM inverter,but also the optimal switching SVPWM technique deduced from three-phase SVPWM technique could be applied to the single-phase inverter.
