What is a frequency inverter?

Frequency inverters are electronic devices that let you control the speed of an AC motor. Background: If electric motors or AC motors are operated directly from an AC voltage supply system, they can only avail of a fixed speed based on the number of poles and the supply frequency of the power supply system on location.

How many companies are involved in inverter production?

Companies involved in Inverter production, a key component of solar systems. 12 Inverter manufacturers are listed below. List of Inverter manufacturers. A complete list of component companies involved in Inverter production.

What is a current-controlled frequency inverter?

Current-controlled frequency inverters maintain the ratio of current to frequency (I/f) at a constant level at all times and are suitable for use in applications in the high megawatt range. In the lower megawatt or kilowatt range, in contrast, voltage-controlled frequency inverters represent the latest state-of-the-art technology.

What are the different types of inverters?

There are two different types of inverter: current-controlled and voltage-controlled. Their functions differ as follows: Current-controlled frequency inverters maintain the ratio of current to frequency (I/f) at a constant level at all times and are suitable for use in applications in the high megawatt range.

Why should you choose a frequency inverter?

In that sector, an adapted or infinitely variable speed allows for optimized production processes – alongside the additional benefit that drives with speed control ensure energy-efficient operation. Our frequency inverters are available in different designs and with a large number of optional functions that cater to many needs and requirements.

Which case is suitable for voltage-controlled frequency inverters?

In simple terms, the following cases are suitable for voltage-controlled frequency inverters: A rectifier converts the AC voltage supplied from the supply system into DC voltage. A DC link then takes on the task of smoothing and stabilizing this DC voltage.
