Technical FAQs 4

What is a frequency inverter?

Also called Frequency Converter, it's a power conversion device running at mains power (60Hz / 50Hz). The frequency inverter converts a basic fixed frequency (50Hz/60Hz), fixed voltage (220V/380V/480V etc.) to a variable frequency (maximum frequency up to 400Hz), variable voltage (maximum voltage equal to input voltage) to control AC motor speed.

What is the maximum inverter frequency?

The maximum inverter frequency depends on its design specifications, with most commercial models offering a maximum frequency between 10 kilohertz to megahertz.

How does an inverter control a motor?

An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.

How much power does an inverter need?

It’s important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
