Abstract

It is common that a DC/AC converter for three-phase load is designed for controlling two variables (for example, speed and flux of AC motor). An additional degree of freedom can be utilized to minimize the switching frequency, which depends on the voltage of the load neutral point. In this chapter, a methodology of switching frequency minimization is proposed in the framework of the modified hysteresis control. The load neutral point voltage is selected as the third variable to be controlled. First, the tracking system algorithm is developed and then optimization with the switching frequency as a criterion is performed by a proper choice of the reference input for the neutral point voltage. The system accuracy is determined by the width of hysteresis loop and is the same for any switching frequency.
