Application
This is rectifier will used for 800A400V Electro Phoretic Rectifiers (CED Coating).
Introduction of CED Coating
Electrocoating, which is also referred to as electro deposition, electrophoretic deposition, CED Coating, CED Painting or electropainting, is an organic finishing process that uniformly applies thin-film primers and one-coat finishes to metallic substrates.
CED coating is used extensively in the automotive industry. In this process, the component after phosphate pre-treatment is dipped in the bath of E-coat chemicals and given an electric charge. The coating gets deposited on the component and then it is removed from the bath, washed and then baked.
This technology gives an organic finish on metal part/component by electrically depositing paint on it. Cathodic electrocoating are high performance coatings and can withstand the harshness of exterior environment.

IGBT Rectifier Advantages Over SCR Rectifier
Same level of reliability
The quality is same level by using IGBT rectifier as conventional SCR rectifier.
Lower harmonics using multiple pulse transformer
Higher power factor in the whole range
Lower output ripple
Modular design
In case of one module is faulty, stop working won't affect other modules continue running and keep continuous operation of CED coating process
Not affected by input voltage fluctuation
Higher efficiency
High regulation accuracy
Fast response time
Wide output voltage range
Power saving
Through IGBT PWM technology, rectifier conversion efficiency is much higher than conventional SCR rectifier, thus saving power of user dramatically.
