Document Type and Number:
Japanese Patent JP7420347
Kind Code:
B2
Abstract:
To analyze stability of a DC power supply system in which power is supplied from a DC power supply through a DC bus to a plurality of servo devices including an inverter circuit and an electric motor, and reflect the analysis to the details of control.SOLUTION: A design support device, based on system information on a DC power supply system and operation pattern information indicating respective operation patterns of a plurality of servo devices included therein, creates time-series current data indicating a time variation pattern of the total value of current supplied to the plurality of servo devices through a DC bus, based on an output impedance Z(s) of a power supply-side part of the DC power supply system, and an input impedance Z(s) of a load-side part of the DC power supply system, the input impedance Z(s) also being a function of the value of current flowing in the DC bus, outputs information indicating stability of the DC power supply system when the current flowing in the DC bus becomes the maximum value of the created time-series current data, and changes the operation pattern information based on the information.SELECTED DRAWING: Figure 1
