IGBT Rectifier Advantages

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

      2. High conversion efficiency, power saving than SCR rectifier

3. Modular design:

Ø Rectifier won’t break down: in case of one module failed, the rectifier continue working with reduced power

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

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

Ø 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.

Ø Less floor space occupied: the rectifiers can be built on top of each other, making them easy to fit into your plant’s design, optimizing floor space.

Ø 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 (40kA) and voltages (200V DC).

Ø Separate output or parallel running output available: you can let the rectifier module separate output to connect to more tanks, or parallel connecting to get higher current for one tank.

4. Compact size, modular structure, less size and weight than SCR rectifier, don't need forklift

5. Low pollution to grid, power factor>0.94

6. 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 keep much extra capacity and increase user’s investment cost.

7. Lower cost for the same specification

8. Ripple affect comparison with SCR rectifier:

For SCR rectifier, if output voltage is not rated value, ripple is higher, there is effect to plating quality, normally 5% ripple requirement is for current ripple. E.g. If you plate at 6000 amps and 6 volt, then quality will be affected. 

In the IGBT rectifier, because it is high frequency output, so plating quality is not affected even working at half voltage, such as 6 volt.
