Braking with regenerative feedback into the line
supply
The inverter feeds the regenerative power back into
the line supply.
•
Advantages: Constant braking torque; the
regenerative power is not converted into heat, but
is regenerated into the line supply; can be used in
all applications; continuous regenerative
operation is possible - e.g. when lowering a crane
load
•
Disadvantage: Does not function when power
fails
