UPS용 인버터의 LC필터 출력 전압제어를 위한 디지털 제어기 설계
Design of Digital Controller for Output Voltage Control of LC Filter in 3-Phase UPS
초록
This paper presents an observer filter algorithm to estimated the load currents in the output voltage control of 3-phase uninterruptible power supply with deadbeat controller. As the result of the proposed algorithm, the sensors to measure the load currents is not required. The comparison of output voltage controls according to the methods of measuring the load currents is also presented in this paper. The results of comparison are shown by the simulation.
