What is the power factor of the power supply of the induction heating furnace?

High power factor, low harmonics. When the power factor of the induction heating furnace is the best, it can reach 0.95, and it usually works between 0.85-0.9. In addition, there are inevitable harmonics, which cause certain pollution to the power grid. The greater the power of the power supply, the more prominent this problem will be. The new generation power supply must be a power supply with high power factor and low harmonics. The current developing technologies include: multiple rectification technology, fully-controlled power tube plus matrix control or PWM control, series circuit, chopper technology, etc. At the same time, it also gave birth to the development and production of harmonic elimination devices for power harmonic filtering and power factor compensation.
