要約(日本語): Stability studies of an independent control for multiple uninterruptible power supplies (UPS) connected in parallel have been discussed previously. However, with the recent development of a compensator for the control equation of the output voltage amplitude, stability of this enhanced independent control was not proceed before. With this compensator, the control equation can employ a high proportional gain without reaching the voltage limiters. This paper shows the results of a stability analysis of the independent control with the voltage drop compensator by means of root locus diagrams of a small-signal model, which represents a system with two UPS's connected in parallel.
