Title:
SYSTEM WITH COMMON POSITIVE AND NEGATIVE BUS BARS, REGENERATIVE CONTROL DEVICE, AND REGENERATIVE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/183200
Kind Code:
A1
Abstract:
The system with common positive and negative bus bars has motor drive devices for individual driving of corresponding motors which are supplied with electric power from common positive and negative bus bars. The motor drive devices execute regenerative control on the basis of a regenerative control start voltage, performs control to stop the regenerative control on the basis of a regenerative control stop voltage, individually calculates a regenerative load factor, and controls the validation/invalidation of the regenerative control on the basis of a comparison result of the calculated regenerative load factor with a preset regeneration-permitting load factor.
