I.G.B.T rectifier means insulated Gate bipolar Transistor, It convert AC (Alternating Current) to DC (Direct Current). Electroplating and similar processes require a low voltage direct current (DC) electric supply, for small scale and experimental operation of electroplating and other electrolytic processes. It is often more convenient to use a three phase SCR & Oil cold transformer-rectifier unit.
I.G.B.T switched mode power supplies have many advantages over SCR & oil cold rectifiers therefor now being used more and more for electroplating processes to replace all types of old rectifiers. High conversion efficiency, power saving at least 15% then SCR & oil cold rectifiers for example 1000 Amp 12 volt plating rectifier, suppose 6300 hour running time one year, saving power 18613kwh then SCR rectifier.
Benefit of I.G.B.T Rectifier
- Less floor space occupied
- Easy to install and maintain
- Low AC current ripple below 5%
- 20% shorter time needed for plating
- Reduce current rating to save power
