Title: Lag reactive power adjusting device using thyristor
Inventor: HIMEI TOYOJI
IPC: G05F1/70
Filed: 1981-10-30
Abstract: PURPOSE:To realize low distortion, and also to protect overvoltage of a thyristor element, by connecting a thyristor in series to 2 windings which are magnetically coupled with each other and have equal self-inductance, and connecting them in parallel. CONSTITUTION:A peak value IP of an electric power supply current within a range 0 deg.-90 deg. where both thyristors 3, 4 conduct simultaneously is varied by a coupling coefficient K. In case of this invention, however, -K<K<0. Qalpha/Q0 denotes magnitude of control capacity, and the larger K is and the nearer (alpha) is to 0 deg., the larger Qalpha/Q0 becomes. When overvoltage has been generated, the thyristor element is protected by making one thyristor conductive, and voltage applied to one thyristor in that case is VTh=(1+K)e by denoting (e) as supply voltage (instantaneous value). Accordingly, in case of -1<K<0, voltage applied to the thyristor is suppressed lower than supply voltage.
