Abstract

This method is used in automated, alternating current drives. It allows the improvement of the congruous composition of the inverter's starting tension. According to this method, a bearing high-frequency signal and a tri-phase system modulating signal, varying according to a sinusoidal law, are formed and compared, while the carrying signal is with a saw-shaped or triangular form and is formed by obviating, representing parts of the sine curves, equidistant to the modulating voltages. The cross points of the bearing and modulating signals determine the switch moments of the tension inverter's power switches.
