Abstract
본 발명은 전원 전압의 급변에 의한 토크 쇼크를 작게 하기 위한 것이다.The present invention is intended to reduce the torque shock caused by sudden changes in the power supply voltage.
역병렬 접속의 사이리스터 변환기(2)에 의해 직류 전동기(1)을 구동 모드 또는 흡수 모드로 운전하고, 속도 제어부(6)의 마이너 루프에 전류 제어 증폭기(7)을 설치하여 전류 제어를 행하며, 전류 제어 신호는 바이어스 증폭기(10)과 노이즈 제거용 적분기(13)을 통해 위상기(14), 게이트 펄스 발진기(15)에 의해 사이리스터 변환기의 사이리스터 점호 위상 제어로 함에 있어서, 전원 전압 검출치(VAC)와 기준 전원 전압(VAC0)의 편차(△VAC)에 따라 적분기(13)으로의 보정 입력 신호(α)를 얻음으로써 전원 전압 급변에 대한 제어 위상 보정을 행하고, 이 보정에 감도 조정기(25) 및 승산기(26)에 의해 전압 변동분에 대한 제어 위상각의 감도를 조정하며, 또는 직류 변동기의 구동/흡수 모드에 의해 보정 극성 전환 회로(27)로 극성을 바꾼다.The thyristor converter 2 of the anti-parallel connection operates the DC motor 1 in the driving mode or the absorption mode, and installs the current control amplifier 7 in the minor loop of the speed control section 6 to perform current control, and the current The control signal is the thyristor firing phase control of the thyristor converter by the phase shifter 14 and the gate pulse oscillator 15 through the bias amplifier 10 and the noise removing integrator 13, and thus the power supply voltage detection value (V AC). Control phase correction for power supply voltage sudden change by obtaining the correction input signal? To the integrator 13 according to the deviation ( ΔV AC ) of the reference power supply voltage V AC0 ). 25) and the multiplier 26 adjusts the sensitivity of the control phase angle to the voltage variation, or changes the polarity to the corrected polarity switching circuit 27 by the drive / absorption mode of the direct current regulator.
