Abstract

PURPOSE: To enhance the accuracy of the motor current control by using two units of the electromagnetic amplifier containing the synchronized AC power source whose output changes according to the control input and which features an equal output phase only when the control input has a specified value and then obtaining the ON/OFF control command in accordance with the difference polarity of these output phases.
