High frequency inverter

What is a high-frequency inverter?

The high-frequency inverter first inverts low-voltage direct current into high-frequency low-voltage alternating current through high-frequency DC/DC conversion technology; then, after being boosted by a high-frequency transformer, it is rectified by a high-frequency rectifier and filter circuit into electricity, usually above 300V. High-voltage direct current, and finally through the power frequency inverter circuit, 220V power frequency AC power is obtained for the load.
Since the high-frequency inverter uses high-frequency magnetic core materials that are small in size and light in weight, the power density of the circuit is greatly improved, As a result, the no-load loss of the inverter power supply is very small and the working efficiency is improved. The peak conversion efficiency of high-frequency inverters used in general small and medium-sized PVS can even reach more than 90%.

Understand the difference in working principles between high-frequency inverters and power-frequency inverters

The high-frequency inverter circuit is more complex. The high-frequency inverter usually consists of an IGBT high-frequency rectifier, a battery converter, an inverter, and a bypass. The IGBT can be turned on and off using control of the driver applied to the gate. The switching frequency of an IGBT rectifier is usually from a few kilohertz to tens of kilohertz, or even as high as hundreds of kilohertz, which is much higher than that of a power frequency inverter. Therefore it is called high frequency inverter. The power frequency inverter is designed based on traditional analog circuit principles and consists of a thyristor (SCR) rectifier, IGBT inverter, bypass, and power frequency boost isolation transformer. Because the working frequency of the rectifier and transformer is both power frequency 50Hz, it is called a power frequency inverter as the name suggests.

Stable Power Supply with Huayite Solar Inverters

Huayite High-frequency solar inverters are used in solar energy systems to convert direct current (DC) to alternating current (AC) to provide a stable power supply for household appliances.

Huayite Solar Inverters: Off-Grid and Grid-Connected Options

Huayite High-frequency solar inverters are divided into off-grid solar inverters and grid-connected solar inverters. Grid-connected High-frequency solar inverters must be connected to the grid to work, while off-grid inverters can generate electricity independently anytime, anywhere, without connecting to the grid. If you choose Huayite High-frequency solar inverter, you can choose RS485 or APP (WIFI or 4G) remote real-time battery-free inverter data.
