Three-phase induction motors are increasingly being used in industry, households, and transportation because they are simple to construct, relatively inexpensive, and easy to maintain. However, harmonic currents are produced by a three-phase inverter using PWM on a three-phase induction motor. Therefore, it is necessary to control current ramp comparison current control for inverters on three-phase induction motors. This is expected to improve the quality of the resulting THD. The simulation results show that for a frequency of 30Hz, a rotational value of 800 rpm and a THDi (current) of 29.29% per phase R are generated. Meanwhile, for a reference frequency of 60 Hz, a current THD value of 5.40% per phase R and a rotational speed of 1200 rpm are generated. The larger the reference frequency, the lower the current THDi. Meanwhile, it is known that the higher the reference frequency, the higher the rotation speed.
