Abstract :
A new PAM method to reduce the torque ripple in an induction motor without producing an optional pulsating wave in a DC link is proposed. A modulating signal has a flat portion of 120-degrees. By using the proposed modulating signal, the amplitude of the fundamental component is increased to about 17 percent more than that of a conventional sinewave inverter; the switching loss is decreased and the motor driven by the PAM inverter produces approximately constant torque.<>
