Korkeataajuisen invertterin toimintaperiaate sisältää pääasiassa pienjännitteisen tasavirtakulman muuntamisen korkeataajuiseksi matalajännitteiseksi AC-tehoksi korkeataajuisen DC/AC-muunnostekniikan avulla., sitten tehostamalla sitä suurtaajuusmuuntajan kautta, rectifying it into high-voltage DC power through a high-frequency rectification and filtering circuit angle, and finally obtaining 220V power frequency AC power through the power frequency inverter circuit for load use. The key to this process lies in the use of small and lightweight high-frequency magnetic core materials in the high-frequency inverter, which greatly improves the power density of the circuit, reduces the no-load loss of the inverter power supply, and improves the inverter efficiency. Usually, the peak conversion efficiency of high-frequency inverters reaches over 90%. kuitenkin, high-frequency inverters also have significant drawbacks, such as being unable to connect to full load inductive loads and having poor overload capacity. twelve

High frequency PWM technology (pulse width modulation technology) is used to convert phase alternating current in a circuit into a sine wave of a certain frequency, making it close to the AC power of the mains. This technology ensures that the operation of the inverter is not affected by load changes to protect high-frequency inverters and electrical equipment.

The working principle of the inverter also includes the current from the power supply entering the inverter and passing through a rectifier to convert direct current into periodic alternating current. In this process, AC power is used to supply DC power, usually using solar panel corners or battery corners
