摘要

提出了一种脉宽调制(PWM)算法，利用参考电压的空间矢量分量产生PWM逆变器的开关命令。这种方法直接计算线路电压。相应的占空比量表示三相的切换顺序以及切换瞬间的距离。并与空间矢量调制和相位电压调制进行了比较。讨论了选择零分量的不同可能性，这是充分利用电压所必需的

Line voltage modulation-a new possibility of PWM for three phase inverters

A PWM (pulse width modulation) algorithm is proposed by which the switching commands of a PWM inverter can be generated from the space vector components of the reference voltage. In this method the line voltages are calculated directly. The corresponding duty cycle quantities indicate the switching sequence of the three phases as well as the distances of the switching instants. The method is discussed in comparison with space vector modulation and phase voltage modulation. Different possibilities of choosing the zero component which is necessary for full voltage utilization are discussed.<>
