A power conversion device meant for converting fixed voltage as well as frequency to different levels of frequency is known as variable frequency drive. It is also known for controlling the speed of voltage and frequency used in power systems. However, VFD allows AC motors to operate at variable speeds.
What are the benefits of using a variable frequency drive?
VFD is the most useful component extensively used in industrial and commercial places. In the houses where the problem of high and low voltage influences, VFD can be installed to regulate the power supply. Hence, some of the benefits explained below-
Enables progressive measure ignition- Some motors do not need a complete jolt to start. The use of variable frequency drive is significant in such cases. It measures the original output required and grants the necessary power to begin the device.
Cost-effective- When VFD installed, and overall energy consumption reduction is observed. A smooth output of voltage is executed at the same time-frequency administered is by the variable frequency drive device. It increases the durability of the machinery for which it gets installed.
Smooth operations- The VFD device prevents a sudden jolt or excessive power input. It gradually gives strength to the motor or electrical equipment to begin. The machinery receives this way substantial voltage is curtailed and power as per its capacity.
Smooth and slow landing- Slow landing means that with the help of variable frequency drive machinery does not halt all of a sudden. It operates with full force and allows us to stop by keeping the frequency of the voltage at minimum levels.
Durable and long-lasting- While it is a cost-effective tool used almost in every domestic and commercial place, it gives the foremost benefit of longevity. The life of the machinery, as well as variable frequency drive, enhances.
Different Types of VFD
There are three distinct kinds of VFD available in the market:
- CSI, i.e. current source inversion used for industrial processing as well as generation of power.
- PWM, i.e. pulse width modulation- These are used for encoding messages into a pulsing system. It controls the rotation of the electrical motor.
- VSI, i.e. voltage source inversion- This type of variable frequency drive is least preferred due to its very less power supply facility.
