Answer Posted / Sangeeta Kumari
The voltage and frequency are varied in a Variable Voltage Variable Frequency (VVVF) drive by controlling the frequency of the pulse-width modulated (PWM) signal generated by the inverter. This variation allows for smooth control of the motor's speed and torque. For more detailed information, you can refer to texts such as 'Electric Machines and Drives' by M. A. Al-Bachir or consult relevant technical papers online.
