3. Why Green Power's switch mode power supplies could replace SCR rectifier? 

Green Power's Switch mode power supplies have many advantages over SCR rectifier, therefore, they are now more and more used for electroplating process to replace SCR rectifier. 

The main advantages of Green Power pulse IGBT plating rectifiers over thyristor rectifiers(SCR) include but not limited to:

● Same high reliability as SCR rectifier, long time 7 days 24 hours continuous running

● High conversion efficiency, power saving at least 17% than SCR rectifier. E.g for 1000A 12V plating rectifier, suppose 6300 hours running time one year, saving power 18,613kwh than SCR rectifier.

● Not affected by power fluctuation, 100% output, don't need extra capacity

IGBT rectifier adopts AC-DC-AC-DC topology, 3 phase AC is firstly converted to DC, which has capacitors for energy charging and discharging, it will suppress power fluctuation, so rectifiers don't need bigger capacity than actual use. 

SCR rectifier doesn't have energy buffer function, it is affected directly by the grid power fluctuation, so it always keeps much extra capacity and increase user's investment cost.

● Pulse output needs less plating time, customer feedback 40% shorter time needed for plating

● Modular design, the advantages of modular design:

  • Rectifier won't break down: in case of one module failure, the rectifier continues working with reduced power

  • Less downtime and easy recovering: plug-in structure, replacing module directly, downtime is shorten to minimum, this reduces potential high cost of your plant stop and increase your plant's availability and productivity.

  • Current expansion available: thanks for the modular design and supporting parallel connection, if you need more power, you only need to add more modules.

  • Reduce current rating to save power: if you don't need all modules working, you can switch off some modules, rectifier can work at lower rating.

  • Less floor space occupied: the rectifiers can be built on top of each other(rack mounted), making them easy to fit into your plant's design, optimizing floor space.

  • Easy to install and maintain: each rectifier consists of up to ten modules and naturally two or more stacks can be connected to allow higher currents (up to 40kA) and voltages (up to 200V DC).

  • Separate output or parallel running output available: you can let the rectifier modules with separate outputs to be connected to more tanks, or in parallel connecting to get higher current for one tank.

● Compact size, modular structure, e.g. air cooling 1000A 12V size only 525*600*310mm, weight is only 58kg. much less size and weight than SCR rectifier, don't need forklift

● Lower cost for the same specification
