| Abstract |
The design of AC motor controllers either for high dynamic performance or for low cost drives still suffers from the complexity of the circuits. With the creation of specialised integrated circuits for AC motor control part count and cost can be reduced. A gate array for pulse width modulation (PWM) and a cell design for the evaluation of an incremental encoder are presented. Both ICs show higher resolution and speed compared with discrete designs. As shown in the experimental results of an induction motor servo drive the ICs help to reduce the delay in the current control loop and to eliminate the noise of the drive by increasing the switching frequency beyond the audible range. |
