2 4 pulse wave intermediate frequency power supply is a power supply composed of 4 sets of rectifier circuits, and the harmonics are less than 12 pulse wave intermediate frequency power supply .

24 the pulse wave frequency power supply is a large power , the large tonnage of induction melting furnace , medium frequency induction furnace , medium frequency melting furnace , intermediate frequency furnace and induction furnacededicated power supply. 
24 pulse frequency power supply in accordance with the circuit into the structure . 4 Species frequency power supply .

1, two sets of rectifiers are connected in series to form two groups, two groups are connected in parallel, and the inverter is connected in parallel to the intermediate frequency power supply.

2 , two sets of rectifiers are connected in series to form two groups, two groups are connected in parallel, and the inverter is connected in series with the intermediate frequency power supply.

3 , four sets of rectifier parallel , inverter parallel intermediate frequency power supply

4 , four sets of rectifier parallel , inverter series intermediate frequency power supply

2 4 pulse wave intermediate frequency power supply, 4 sets of three-phase rectification form 24 pulse rectification, low harmonics generated by 24 pulse wave intermediate frequency power supply are cancelled on the high voltage side, the lowest harmonic is from 23 times, according to harmonic analysis, harmonic order The higher the component, the lower the harmonic generated by the 24-pulse rectified power supply is less than the 12-pulse IF power supply.

For example, a large-tonnage 20-ton intermediate frequency furnace uses a 24-pulse intermediate frequency power supply .
