要約(英語): Uninterruptible power supplies (UPSs) are fundamental components of the power systems of important infrastructure facilities. However, in UPSs, the output voltage must be precisely controlled under load variations. For large-scale UPSs, the power rating of the inverter is several hundred kVA or more and its switching frequency must be under several kHz. The carrier interval is thus large, deteriorating its robustness to load disturbances. Hence, this paper proposes a deadbeat control with disturbance compensation using a 1-MHz multisampling method for three-phase pulse-width modulated inverter systems. Using an FPGA based hardware controller, 1-MHz sampling is realized within the carrier interval of the pulse-width modulated pulse. Simulation and experiments show that the robustness to load variation is better than that of the conventional deadbeat control method.
