With the increasing cost of energy, industries have started to worry a lot about how best to use energy while protecting the machines from surges and other power supply quality issues. To use and regulate energy coherently, variable frequency drives, or VFDs, are primarily utilized in a variety of industrial electrical equipment, including motors, fans, pumps, and many others. Variable frequency drives are being widely utilized for energy saving in a variety of industries, including chemical, oil and gas, mining, power, and commercial structures. S.C. Industrial Syndicate, one of the top variable frequency drive dealers in Mumbai, offers customized VFD solutions for a range of industrial machines.
Key Benefits of a Variable Frequency Drive
Because of having numerous benefits, VFDs are mainly used to control the speed of electric motors. Following is a list of just a few benefits that encourage industrial engineers to use variable frequency drives for monitored and managed control of machines at the least involvement of humans:
- Cuts Down on power line interruptions
- Reduces power consumption when a motor starts
- With VFD, a motor can be started at zero frequency
- Motors start at controlled voltage and current
- VFD allows regulating and managing torque limits as per requirements
- VFD allows for more operating speed adjustments
- VFD improves motor acceleration as well as smooth stopping
- VFD facilitates the removal of gearboxes and other mechanical driving components in some cases
Various Types of VFDs
Variable frequency drives can be divided in three major categories-
- Voltage-Source Inverter (VSI) VFD: It is the most popular kind of VFD. It uses a basic diode circuit with a capacitor to store energy and to convert the AC signal into a DC signal. An inverter circuit transfers the energy, stored in the capacitor, to the output by.
- Current-Source Inverter (CSI) VFD: CSI generates a smooth output dependent on the changeable voltage range; it relies on current rather than voltage. A thyristor bridge inverter is used instead of a diode bridge rectifier to create a square wave current.
- Pulse Width Modulation Inverter (PWM): PWM VFD provides a more sinusoidal current output to manage and control voltage and frequency for an AC motor. PWM VFDs are relied for being more efficient and providing high performance. PWM VFD has a converter, control logic, an inverter, and DC link.
