Common Bus Power Supplies use a common rectifier to supply power to the DC bus for all the DC-AC inverters. Power-sharing on the DC bus increases the efficiency of applications where inverters are motoring while others in the same process are generating power.
Bulletin 20S SCR Bridge is a non-regenerative DC bus supply that supplies power to AC drives that have a common DC bus input. The supply converts incoming three-phase AC line voltage to a common DC bus voltage. You can configure this supply for stand-alone and master-slave applications.
Bulletin 700AFE Active Front End (AFE) is a regenerative DC bus supply that supplies DC power to a line-up of AC drives that have a common DC bus input or a single common bus drive. The AFE allows regeneration to the AC power line and provides low harmonics to meet IEEE-519 requirements.
