Title: White Paper: Common Bus and Line Regeneration: Addressing VFD Applications when Regenerative Energy is Present
Number: WP.AFD.14
Date: 09/14/2015
Description: Regenerative energy is present when a motor is braking or overhauling due to the load. This causes the motor to act as a generator with the energy flowing back into the VFD. The diode bridge will stop current from flowing back to the line; thus charging up the DC bus capacitors and potentially causing faults due to high DC bus voltage. In this article, we will address this challenge by comparing various solutions which use line regeneration and common DC bus arrangements.
