Kinetic Energy Buffering
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.
