above is the comparison of intermediate frequency power supply . I hope everyone will pay attention when purchasing intermediate frequency power supply . KGPS power supply intermediate frequency power supply is a parallel resonant melting furnace, with good cost performance, relatively large consumption and low power factor; KGPS-CL power supply intermediate frequency power supply is series resonance melting . Furnace, with high cost and guaranteed power factor of more than 0.95, has become popular in recent years; IGBT power supply intermediate frequency power supply is also series resonance, but IGBT module operating conditions are relatively harsh, and the failure rate is higher than that of thyristor, and its use has gradually decreased in recent years. Comparison of intermediate frequency power supply , I hope everyone can help.
