High frequency inverter adopts high frequency transformer booster inverter circuit. It first through the high frequency DC/DC conversion technology, the low voltage DC inverter into high frequency and low voltage AC, and then through the high frequency transformer booster, and then through the high frequency rectifier filter circuit rectifier into usually 300V above high voltage DC; Finally, through the power frequency inverter circuit to obtain 220V power frequency AC for load use.

Because the high frequency inverter is small size, light weight of the high frequency magnetic core material, thus greatly improve the power density of the circuit, so that the inverter no load loss is small, high inverter efficiency.
