Application
This is rectifier used for High Frequency IGBT Plating Power Supply 1500A 2000A 15V for Plating Line.
IGBT Rectifier working Principle
Three phase AC input is converted to DC through rectification and filter, then DC voltage is transformed to DC output through phase shift full bridge PWM DC/DC converter.

Comparison between IGBT rectifier and SCR rectifier
1. Power saving above 17%
2. Less affected by power fluctuation
3. Same high reliability as SCR rectifier, long time 7 days 24 hours continuous running
4. Pulse output needs less plating time, customer feedback 40%shorter time needed for plating
5. Compact size
6. Low pollution to grid, power factor>0.93
7. Lower cost for the same specification
8. Modular structure, high reliability, one module break-down won’t affect other modules running, rectifier don’t stop, don’t need to stop plating line.
