Hydrogen generating by water electrolysis is a widely recognized
and relatively mature method for hydrogen production. The power
supply is the basis of whole hydrogen generating equipment, so
there are strict requirements for power supply stability. For this
product, we adopt double reverse-star type rectifying circuit,
triggering pulse of thyristor, and digital controller, making
equipment highly automatic and high reliability. Now our silicon
controlled power supply (KGHS series) have been customized up to
10kA current, is widely applied for this industry by cooperating
with hydrogen generating equipment companies and EPC projects.

1- which is better air or water-cooling?
The environment where the rectifier will be used and output power
determines the best type of cooling. For harsh, corrosion, sealed
or high temperature environments water-cooling is best suitable.
For the lower output power(such as lower 3000A current), the
air-cooling is economical and practical.
2- what is the advantage of IGBT rectifier comparing with silicon
Smaller size and lighter weight, more energy-saving.
3- what kinds of rectifier you supplied?
We customize any specifications(500A~20ka or DC 12V~200V)
equipments for electroplating rectifier, water electrolysis
rectifier, copper/zinc/nickel/lithum/lead electrolysis refining
rectifier, anodizing power supply, induction heating power supply.
