5.12 Kinetic Energy Buffering Operation

When the input power supply is disconnected, the inverter's DC link voltage decreases, and
a low voltage trip occurs blocking the output. A kinetic energy buffering operation uses
regenerative energy generated by the motor during the blackout to maintain the DC link
voltage. This extends the time for a low voltage trip to occur, after an instantaneous power
interruption.
