What is the difference between variable frequency power supply and frequency converter

When it comes to power supply, we may all know that it is an auxiliary device for charging electrical appliances, but many people do not understand what is a variable frequency power supply. The times are advancing, the electrical appliances are updating, and the auxiliary equipment is constantly changing. In order to facilitate your understanding, the editor will explain the difference between variable frequency power supply and frequency converter, and understand these auxiliary equipment. I believe you will understand the purchase principles in the future. Let's study together.

The whole variable frequency power supply circuit is composed of enterprises such as information exchange, constant current, AC and filtering. Therefore, the output voltage and current signal waveforms are pure sine waves, which are easy to approach the ideal social AC power supply system. The grid voltage and frequency can be output to any country in the world.

Principle and main functions of the frequency converter: the frequency converter is an electric energy control device, which converts the power frequency power supply to another frequency by using the switching function of the power semiconductor device. It can be divided into AC-AC converter and AC-DC-AC converter.

AC-AC frequency converter can directly change AC into AC, frequency conversion and voltage transformation; The AC-DC-AC converter first rectifies the AC current into DC through the rectifier, which is better than the AC10 converter, and then converts the DC current into variable frequency and variable voltage AC through the inverter.
