The high-frequency inverter first uses high-frequency DC/DC conversion technology to invert low-voltage direct current into high-frequency and low-voltage alternating current; then, after being boosted by a high-frequency transformer, it is rectified by a high-frequency rectifier filter circuit to usually above 300V High-voltage DC power; finally, 220V power frequency AC power is obtained through the power frequency inverter circuit for the load.
