Series Inverter Medium Frequency Power Supply

The series inverter medium-frequency power supply is an efficient, energy-saving power device, widely used in metal heating, smelting and heat treatment.

Its working principle is to generate an alternating magnetic field through the inductor, inducing current in the metal workpiece to achieve rapid heating. By adjusting the inverter frequency, it realizes power regulation. During the oven drying and heat preservation of the medium-frequency electric furnace, the rectifier thyristor stays fully on, which improves the power factor and avoids high-order harmonic pollution to the power grid. It also supports functions such as one dragging two or three.
