Abstract

PURPOSE: To supply an electric motor with a current of little higher harmonic and reduce the torque ripple of the motor, by coupling two cyclo converters with each other.
CONSTITUTION: When an induction motor 2 is driven at frequency not equal to one fifth or one seventh of power frequency, two cyclo converters 1A, 1B are driven by load-side commutation instruction signals with a phase angle of 180°. When the motor 2 is driven at frequency equal to one fifth or one seventh of the power frequency, the cyclo converters are driven by load-side commutation instruction signals with a phase difference of 180°. This results in supplying the induction motor with a current which has a symmetric wave form and little higher harmonic.
