By doing so, the v/f model prevents issues like magnetic saturation and. . The most popular algorithm for the control of a three-phase induction motor is the V/f control approach using a natural pulse-width modulation (PWM) technique to drive a voltage-source inverter (VSI), as shown on Figure 1-1.
