IGBT power supply is a new type power semiconductor device and controlled by IGBT

The IGBT power supply is a new type power semiconductor device and controlled by IGBT(insulated gate bipolar transistor, manufactured by Siemens, Germany). It’s modular type series resonant power supply which used in induction heating equipment and it can replace the KGPS SCR MF power supply.
1. Constant output power and fast melting speed are the main feature of IGBT power supply. Besides, not same as SCR power supply adjusts voltage to adjust power, IGBT power supply will adjust frequency to adjust power. And never be affected by the material quantity in furnace and thickness of lining, the power is outputted constantly all the time. Especially in melting the poor magnetic conductivity material such as stainless steel, copper and aluminum, the IGBT power supply is superior with the characters of fast melting and less part burned.
2. Power saving: As the inversion is IGBT half-bridge inversion, with higher inversion voltage of 2800V, the inversion current is less than KGPS power supply for 4 times. So the power consumption of IGBT power supply is less power consumption than normal SCR power supply for 10%.
3. No high degree harmonic effect to grid. The 3 phase full wave rectification, no frequency order and no conduction angle need to be adjusted are adopted in IGBT power supply, the DC voltage is working at the max value all the time.
4. The frequently start is successful 100% by the reason of series inversion technology is applied.
5. High power factor which is more than 0.95 and less reactive loss.
