Switch Mode Rectifier For Electrolysis Seawater Electrolysis Producing Sodium Hydroxide Chlorine Gas Hydrogen Gas

IGBT switch mode electrolysis rectifier's applicationrangeThe switch mode electrolysis rectifiers as ac dc power supply to provide dc source,Website:http://www.gprectifier.com, for various electrolysis process where need relatively lower power below 500kw, such as Electrolysis ofion-exchange membrane Caustic soda (NaOH), sodiumhydroxide,potassium hydroxide, copper foil, salt solution,seawater desalinationElectrodialysis(ED), DC power supply for nonferrous metals electrowinning from melts (aluminum, magnesium) and solutions (zinc, copper, nickel, sodium, cadmium, lead, manganese, water, etc.);power supply of electrolysis units for gas production Chloro, Fluoro,Hydrogen fluoride, producing chlorine (Cl2) by electrolysis of brinein the process of Chlor-Alkali (CA), and caustic soda and hydrogen are generated together, Chlorine (Cl2) is used as a raw material for the PVC process, isopropyl cyanide process and phenol process.and rectifier for electrolysis of fused salt. For 500kw above power demand for electrolysis, it's recommended to use SCR based rectifier.   Green Power ac dc switching power supply advantages Support parallel or series connection for different number of electrolysis cells parallel or series, you choose capacity yourselfHarmonics<15%, power="" factor="">0.93, minimum impact on supply network15%,High voltage available up to 500VHigh accuracy up to 0.1%High reliability, low fault rate, robust runningLong service lifespanModular design, compact sizeCentralized control and diagnostics using modern microprocessor systems, optimization of process controlHigh performance price ratioDesign to seismic zone and altitudeBlock diagram of the dc rectifiers The switch-mode rectifier is working at the following diagram: The mains rectifier bridge converts the voltage into DC voltage. The IGBT modules power electronicsthen convert the DC voltage pulse width modulated into a alternating voltage. The internal transformerrealizesisolation and voltage adjustment on the secondary side. On the output side rectification is achieved by fast power diodes. Aconstant smoothed and fully controllable DC voltage is generatedatthe output side.
