POWERFACTOROF THYRISTOR-CONTROLLEDWITH SINUSOIDALSUPPLYVOLTAGEAND INTEGRAL-CYCLE TRIGGERING
T. G. BlandandWilliamShepherd · 1977
A single-phase, thyristor-controlled resistive or series resistance-inductance load,withsinusoidal supply voltage,hasa powerfactorthatcanbe attributed to a combination of active,reactive(displacement) and distortion voltamperes. Forresistive loadsitisfouind that,forbothsymmettricalphase-angle triggering andintegral-cycle triggering PowerFactor = Power-(pu) For seriesR-Lloadswithphaseangle4= tan uL/Rand integral cycletriggering thepowerfactorclosely approximates therelation
