Technical FAQs 4

What is a frequency inverter?

A frequency inverter is an electronic device that converts the fixed frequency and fixed voltage from your electrical supply (e.g.,50Hz or 60Hz,240V or 480V)into a variable frequency and variable voltage output.This allows the operator to precisely control the speed and power of a standard AC induction motor.

How does a frequency inverter convert fixed power to variable power?

The process of converting fixed power to variable power involves three key stages: Rectification (AC to DC):The frequency inverter first takes the incoming Alternating Current (AC)power and converts it to Direct Current (DC)using a component called a rectifier.This DC power is stored in a DC bus (a set of capacitors).

How does an inverter output an AC waveform?

In summary, the inverter can output an AC waveform of variable frequency (and adjustable RMS voltage) by modulating the pulse widths of DC voltage pulses – this PWM output is how the VFD generates a new AC supply for the motor.

What is inverter voltage?

Inverter voltage (VI) is an essential concept in electrical engineering, particularly in the design and operation of power electronics systems. It describes the output voltage of an inverter, which converts direct current (DC) from sources like batteries or solar panels into alternating current (AC).
