How does a frequency inverter work?

Frequency inverter relies on the internal IGBT to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving and speed regulation.

What is a high frequency inverter?

In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.

What is the basic design of a frequency inverter?

The basic design of a frequency inverter consists of just electronic components, without any mechanically moving components. Frequency inverters are made up of the following main assemblies: The rectifier converts the AC voltage on the input side into DC voltage.

Can a frequency inverter run a motor above 50Hz?

While most motors are designed to operate at a frequency of 50Hz, there are many situations where higher speeds are necessary. Frequency inverters provide the flexibility to run motors above 50Hz, allowing for increased operational speeds and improved performance in certain applications.

What happens when a frequency inverter drives a motor?

When a motor is driven by a frequency inverter, the behavior of the motor’s torque changes with the frequency of the supplied current. At lower frequencies, the inverter’s output torque typically decreases.

How to choose a frequency inverter?

1. Appropriate Frequency Range for Different Applications One of the most critical aspects of frequency inverter operation is selecting the right frequency range for the specific application. For most industrial applications, the standard range of 0-50Hz is sufficient, especially for typical motors.
