| 摘 要： | 基于SPWM对称规则采样波形与SVPWM波形相似的特点,由SPWM的调制隐函数推导出SVPWM的调制隐函数,并对其进行分解,得出SVPWM的简化算法.该算法直接利用三相参考电压瞬时值计算PWM信号的开关状态切换时间,无需坐标变换、三角函数运算、扇区判断和有效矢量作用时间的计算.分析了死区效应以及SVPWM算法中电压矢量...

| Abstract: | SPWM symmetric and regular sampling waveform and SVPWM waveform is similar.SVPWM modulation im-plicit function is derived from SPWM modulation implicit function.SVPWM simplified algorithm is obtained from the decomposition of SVPWM modulation implicit function.The algorithm directly use the instantaneous value of three phase reference voltage to calculate PWM signals switching time of switch state.It doesn't need coordinate transforma-tion,trigonometric calculations,sector determinement and calculation acti... |
