The rectifier part of the series power supply is always fully open. Therefore, the dc voltage output is stable without reducing power factor and increasing harmonic content. The series inverter can output rated power in either cold state or hot state, with half charge or full charge. The series inverter always operates at rated output during the whole melting process. The rectifier voltage of series inverters is not controllable, and the power output can be changed by controlling the inverters, so the rectifier can supply power to two or more inverters at the same time, realizing double or multiple power supply of one power source. Two or multiple furnaces get the power at the same time, without any switching switch between the electric furnaces, in two or more electric furnaces, the power can be adjusted arbitrarily in the range of 0% - 100%.
high power factor: ≥95%
Low harmonic, reduce pollution to power grid
Saving energy about 20%
One power can supply two or multiple furnaces at the same time
The parallel power supply adjusts the power through the rectifier. The variable frequency power has lower technical requirements for components and the cost of components is lower. So, manufacturer can reduce the cost of production. After years of use and development, Parallel power supply has stable performance with favorable price, which is suitable for low investment and the initial stage of the user.
Wide application range
mature technology
simple maintenance
good cost performance
The variable frequency power can choose KGPS power or IGBT power. KGPS power uses SCR (silicon controlled) as inverter component. IGBT power uses IGBT (Insulated Gate Bipolar Transistor) as inverter component.
KGPS power: The advantages of this kind of power supply are mature technology, reliable quality, cheap price, the disadvantage is that the electrical efficiency is 10-20 percentage points lower than IGBT intermediate frequency power supply.
IGBT power: The advantage is that the electric efficiency is high, generally up to 90% or more. Therefore, the power saving ratio of silicon controlled power supply is 10-20 percentage points.
