| 摘 要： | 为提高单相PWM全桥逆变器的效率,将空间矢量脉宽调制(SVPWM)应用于单相逆变器。通过单相SVPWM与其等效三角波调制的比较,分析彼此的本质联系。参照三相SVPWM零电压矢量选择技术,将降损开关模式应用于单相SVPWM逆变器。与传统开关模式相比较,降损开关模式可降低开关损耗50%并延长开关管寿命。实验结果验证了单相SVPWM技术的优越性。

| Abstract: | In order to increase the efficiency of the single-phase PWM full bridge inverter,the SVPWM method is used in the single-phase PWM full-bridge inverter which based on the analysis of space voltage vector.And the essential relationship is proved through the comparison of the SVPWM method and the equivalent triangle wave modulation method.According to the zero-voltage vector selection techniques in three-phase SVPWM,a loss reduction switch mode is applied in a single-phase SVPWM inverter.By comparison of gener... |
