a) what is regeneration? When Motor works as Generator – it is called as Regeneration. Whenever Load pulls the motor, at that time speed of the rotor is higher than the set speed of motor so motor will work as generator – this is called regeneration
Depends upon system For common DC bus sytem only antiparallel IGBT is enough so that any regeneration from any of the drive will give DC power back to DC bus and that can be used by other system connected to this Bus – ultimately consumes less power from main incomer For single drive unit, this DC voltage is converted in AC from regeneration circuit and fed back to AC supply using transformer at output (RRU normal uses this)
As per me, it can be for any motors.
Diagram is already posted above by Deep
Yes it will be sine wave because there will not be any switching when regenerative power will be converted from DC to AC Please have a look at attachment for more understandings Rgds, DP AttachmentD7166.pdf (551 Downloads) |
