ઉચ્ચ-આવર્તન ઇન્વર્ટર ઉચ્ચ-આવર્તન ડીસી/એસી રૂપાંતર તકનીક દ્વારા ઓછા-વોલ્ટેજ ડાયરેક્ટ પ્રવાહને ઉચ્ચ-આવર્તન લો-વોલ્ટેજ વૈકલ્પિક પ્રવાહમાં રૂપાંતરિત કરે છે, and then boosts the voltage through a high-frequency transformer, and then rectifies it into a high-voltage usually above 300V through a high-frequency rectifier and filter circuit. Direct current, and finally obtain 220V power frequency AC power for the load through the power frequency inverter circuit. Advantages and disadvantages of high-frequency inverters: High-frequency inverters use high-frequency magnetic core materials with small size and light weight, which greatly improves the power density of the circuit, making the no-load loss of the inverter power supply very small, and the inverse Transformation efficiency has been improved.

Usually the peak conversion efficiency of high-frequency inverters reaches more than 90%. જોકે, it also has significant disadvantages. The high-frequency inverter cannot be connected to a full-load inductive load, and the overload capacity is poor.
