Three-phase inverter modulation coefficient

This calculator provides calculations for three-phase inverter control techniques, specifically focusing on sinusoidal pulse width modulation (SPWM). . However, most 3-phase loads are connected in wye or delta, placing constraints on the instantaneous voltages that can be applied to each branch of the load. It also compares two widely used modulation techniques Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Modulation (SVM) with reference to the losses of a three phase two. . In order to realize the three-phase output from a circuit employing dc as the input voltage a three-phase inverter has to be used. The inverter is build of gives the required output. In this chapter the concept of switching function and the associated switching matrix is explained. [pdf]
