Regen DC Bus Supply

SR32 devices are AC/DC three-phase converters with a full digital control, which are active in the four quadrants to supply constant voltage to the DC link of the AVy and AGy inverters.

The SR32 converter is suitable to supply power to both single and multiple inverter systems connected to a common DC link. A part of the regenerated power can be exchanged between the monitoring and regenerating drives; the exceeding power is regenerated back to the Mains via the SR32 converter. The output voltage of the SR32 converter is kept constant within a specified range even if the inverter operates in a regenerative mode untill it reaches the full current value supplied while functioning in a rectifier mode.This makes it possible to use a SR32-fed inverter in applications requiring a continuous regeneration.
