What is a Variable Frequency Driver?

Variable Frequency Driver (VFD) is a kind of motor controller which is driving a motor by varying the frequency and voltage supplied to the electric motor. Variable Frequency Driver has a more different name, those are adjustable speed drive, adjustable frequency drive, variable speed drive, AC drive, Microdrive, and Inverter. The Variable Frequency Driver (VFD) also gives protection to the safety of AC Induction Motor.

Variable Frequency Driver

In a Variable Frequency Driver (VFD), frequency is directly related to the Motor’s speed. If we define in a simple way, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, then the Variable Frequency Driver low down the frequency and voltage to meet the requirements of the electric motor’s load.

Components of Variable Frequency Driver (VFD)

Variable Frequency Driver (VFD) consists of 4 parts, which are 1. Converter, 2. Inverter, 3. Control Circuit, and 4. Power Supply.

Converter

By using the Converter Circuit, converts AC power into DC power. Here used 3-Phase Rectifier as a converter.

Inverter

By using Inverter, converts DC power into the AC power of variable frequency. In Variable Frequency Driver (VFD), 3- Phase IGBT used as an Inverter.

Control Circuit

The Control Circuit of a Variable Frequency Driver is used to control the Inverter.

Power Supply

Using this power supply Variable Frequency Driver (VFD) can deliver the power to Control Circuit. Here in VFD used SMPS Power Supply. There are used DC 600V as an Input, and the Output is DC 24V. And here the output is Relay type.

Why Variable Frequency Driver (VFD) is Known as an Inverter?

If we define simply about Inverter which is that, to convert DC to AC. If we also want to define converter in a very simple way, which is that to convert AC to DC. When a Variable Frequency Driver (VFD) wants to complete an operation, first of all, VFD converts the AC to DC. After the conversion of AC to DC, the VFD converts the DC to AC 3-Phase. So that’s why Variable Frequency Driver (VFD) is also known as Inverter.

Now You May Ask a Question, why first converts AC to DC and after that again converts DC to AC?

We need to first convert AC to DC and after that again need to convert DC to AC because, in AC mode, there is no option for changing frequency. So that’s why first of all we need to change AC into DC.

Operation of a Variable Frequency Driver (VFD)

When A Variable Frequency Driver (VFD) is in operation mode, first of all, come talk about input. In input, you have to give supply. The important subject is that in the input of VFDs you may give either single-phase or 3-Phase supply, ultimately the Variable Frequency Driver (VFD) will give the output every time in 3-Phase supply. It means that, when a Variable Frequency Driver (VFD) get the supply, it will proceed to the next work or task.
After that, Variable Frequency Driver (VFD) converts the AC supply of input into DC by using a rectifier.
In this step, the Variable Frequency Driver’s (VFDs) controlling circuit gives pulse to the Insulated Gate Bipolar Transistor (IGBT). The variation of frequency depends on the given pulse to IGBT. The controlling circuit of Variable Frequency Driver (PLC) changes the pulse which is given to IGBT by the requirements of the user’s frequency level. For 3-Phase, there is 6 IGBT. In this step, again converts DC to AC and give the output to Variable Frequency Driver (VFD).

Why Should I Use a Variable Frequency Driver (VFD)?

Reduce Energy Cost and Energy Consumption

In industry or factory, if there is an application that does not need to be run at full speed than you can reduce energy costs by controlling the motor with a variable Frequency Drive (VFD). In industries, more than 70% of power is consumed by electric motors.

Easy Installation

Pre-programmed and factory wised Variable Frequency Driver (VFD) offers an easy way to connection and maintenance.

Increase Production Through Tighter Process Control

At the most skillful speed for your applications by operating your motors, fewer mistakes will occur, and thus production levels will increase, which earns your company higher revenues.

Extend Equipment Life and Reduce Maintenance

If industry or factory if they control motors by Variable frequency Driver (VFD), the motor will last longer and will have less downtime due to maintenance. Because of the VFD’s proper control of the motor’s frequency and voltage, the Variable Frequency Inverter (VFD) propose better protection for your motor from these issues: phase protection, under-voltage, electro thermal overloads, overvoltages, etc.

Benefits Of Using Variable Frequency Driver (VFD)

Using variable Frequency Driver, there is a lot of benefits. These are:

If you want to control the speed of a motor, and also want to variation of a motor’s speed as like as your own you can do it. Like that, if you want, the motor will run slow at this moment, that time you can able to slow down the speed of that motor by using Variable Frequency Driver (VFD). If you want, the motor will run speedily in a moment, then you can control the motor by using Variable Frequency Driver (VFD).
If you want to run a 3 Phase motor in your house by using a single-phase line, Variable Frequency Driver (VFD) can do it easily.
By using Variable Frequency Driver, you can run a motor in reverse or forward mode. Also, you can run a motor in Star-delta.

For protecting the motor, Variable Frequency Driver (VFD) keeps Breaking Register in hands that is one kind of protective system.
