Electronic VFDs are speed control devices which vary the voltage and frequency to an induction motor using a technique called Pulse Width Modulation (PWM). Since they are inexpensive and reliable, VFD’s have become the preferred way to achieve variable speed operation. The following is a g...Read more »

Variable Frequency Drives (AC) help to save electrical energy in mechanical machines. The drive allows to reduce the power consumption using Insulated Gate Bipolar Transistors (IGBT) as switch to control the frequency and voltage of the output power. VFDs are available in the market for variety ...Read more »

What are Variable Frequency Drives? They are power conversion devices which convert fixed voltage and frequency to a variable voltage and frequency, controlling the speed of both elements that are used for power systems. Unlike, Tesla’s invention of the 3-phase AC motor, VFDs allow AC moto...Read more »

Variable frequency drives are also referred to as variable speed drives or adjustable frequency drives. They come in three basic types which are current source inversion, voltage source inversion and pulse width modulation. They allow varying speeds to be selected within the range of their opera...Read more »

The whole world uses DC/AC power inverter, a device that can take 12, 24 up to 48 volts direct current (DC) electricity and convert it into 120 volt alternating current (AC) electricity. The converted Alternating Current(AC) can be at any required voltage and frequency with the use of suitable t...Read more »
