In this paper, the authors aim for design and implementation of a Variable-Voltage Variable-Frequency (VVVF) controller based on Pulse Width Modulation (PWM) technique for a single phase and three phase induction motor using VHDL. Variable-Voltage Variable-Frequency (VVVF) technique is used extensively in the industry as it provides the accuracy required. A voltage/frequency (v/f) controlled motors falls under the category of Variable Voltage Variable Frequency (VVVF) drives. To maintain maximum torque under given working condition, the flux in the machine must be maintained constant. The ratio of voltage to frequency must be held constant.
