The BAP-3012 provides complete SCR firing control for industrial/commercial power supplies of any power level, delivering hard firing gate drive power to control larger SCRs from 16mm to 100mm.
The BAP3012 allows the user to take advantage of the benefits inherent to 12 pulse converters. These topologies provide very low output voltage ripple and minimize input harmonic distortion. However, to fully take advantage of dual bridge topologies, the current outputs of each bridge must be properly balanced.
Without the BAP-3012, slight mismatches (.5%) in transformer secondary voltages may result in current imbalances between paralleled bridges as high as 20%.
