Title:
DC BUS CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/261094
Kind Code:
A1
Abstract:
This DC bus control system controls power fluctuation in a DC bus which is connected between an input power supply and a load. The DC bus control system includes: a main stabilization device that has a first charging/discharging element and a first power converter; and a plurality of sub-stabilization devices that each have a second charging/discharging element, a charging element, or a discharging element, and a second power converter. The plurality of sub-stabilization devices each include: a first sub-stabilization device that has a charging/discharging element and the second power converter; and at least one second sub-stabilization device that has a charging element or a discharging element and the second power converter. The response speed of the first sub-stabilization device is determined such that the charging amount of the charging element or the discharging amount of the discharging element in the second sub-stabilization device is changed at a predetermined time constant.
