The high-frequency inverter power supply converts the original low-voltage direct current into low-voltage high-frequency alternating current through DC/DC high-frequency conversion technology, then boosts the voltage through a transformer, and then rectifies the high-frequency rectified and filtered current into high-voltage direct current with an average value of more than 300V v.  Because the high-frequency magnetic core material of the high-frequency sine wave inverter is small in volume and light in weight, the power density of the circuit can be greatly improved, the no-load loss of the sine wave inverter is reduced to be very low, and meanwhile, the conversion efficiency of the sine wave inverter is improved.  The peak conversion efficiency of small and medium-sized high-frequency sine wave inverters can reach more than 90%

Power frequency sine wave inverter：

Sine Wave Inverter, Solar Inverter, MPPT Controller, Inverter Power Frequency Inverter Power Supply is used by converting DC direct current into low-frequency AC alternating current and boosting it to 220V mains supply through a transformer.  The structure of power frequency sine wave inverter is relatively simple, and various protection functions can be realized in low voltage working environment.  In the circuit using the power frequency sine wave inverter, the power supply is stable in operation, strong in anti-interference performance and good in overload capacity, so it is relatively reliable and can suppress higher harmonic components.  However, its size is relatively large, its price is relatively high, and its relative power is also very low.  According to the current manufacturing process, the rated load efficiency of the sine wave inverter is not more than 90%, so under the condition of no load, its loss is large and its efficiency is low.

The above is a summary of the differences between high frequency and power frequency sine wave inverters. It can be seen that at present, high frequency sine wave inverters has more market value.
