Abstract

PURPOSE: Semi-conductor switches are controlled in their on-off condition, output electric current of the invertor is controlled in such a manner as it presents a trapezoid wave form or step-like form and thereby a torque ripple of the load is decrased to eliminate a vibration or noise and further enable an extremely low speed stable operation.
