| Abstract: | In order to improve the waveform quality of the output voltage of uninterruptible power system(UPS),this paper proposes a new combined control scheme for the single-phase UPS based on the fast response characteristic of PID controller and the static error free tracking characteristic of repetitive controller.The improved repetitive controller needs only to detect the output voltage of UPS,so its structure is simple and easy to implement.The prototype of 10 kVA single-phase UPS has been manufactured.Experime... |
