What's the working principle of Veikong vfd or AC drive?
The working principle of Veikong vfd or AC drive is based on controlling the frequency and voltage of the power supplied to the AC motor. It involves the use of a rectifier, a DC bus, and an variable frequency inverter.
1. Rectifier: The rectifier converts AC power from the utility into DC power that is fed to the DC bus.
2. DC Bus: The DC bus is a capacitor bank that stores the DC power from the rectifier. It acts as a buffer and helps to smooth out any fluctuations in the DC voltage.
3. Inverter: The inverter converts the DC power from the DC bus into AC power that is supplied to the motor. The inverter uses pulse-width modulation (PWM) to adjust the frequency and voltage of the power supplied to the AC motor, enabling precise control of motor speed and torque.
The PWM technique used by the inverter involves generating a series of high-frequency pulses and varying their width to adjust the output voltage and frequency of the power supplied to the motor. The width of each pulse determines the amount of power flowing to the motor. By adjusting the pulse width and frequency, the VFI or AC drive can vary the speed and torque of the motor.
In summary, the VFI variable frequency inverter or AC drive works by rectifying the AC power into DC power, storing the DC power in a capacitor bank, and then using an inverter to generate pulse-width modulated AC power that is supplied to the AC motor. By controlling the frequency and voltage of the power supplied, the VFI or AC drive can precisely adjust the speed and torque of the motor.
