Characteristics and Application of IGBT Ultrasonic Induction Heating Power Supply

Characteristics and Application of IGBT Ultrasonic Induction Heating Power Supply

(1) High electrical efficiency of the power supply The inverter output voltage of the IGBT super audio frequency power supply is high, the current is small, and the line loss is small, which is a saving power supply. The power factor is about 10% higher than that of the thyristor intermediate frequency power supply, and it can usually reach more than 90%.

(2) The output power is stable and the IGBT inverter frequency tracks the change of the load. When the resistivity and permeability of the heated metal increase, the working frequency of the power supply also changes randomly to achieve automatic tracking of the full resonant frequency. The automatic adjustment of Xianyuan output power, that is, frequency conversion. So as to achieve stable output power and significantly improve the heating efficiency.

(3) Small harmonic interference to video games The high-order harmonics generated by the IGBT super audio frequency inverter power supply are small, and the harmonic interference to the power grid is very weak.
