Abstract

ABSTRACT
This paper examines the controlled variation of the r.m.s value of the alternating voltage applied to a load through an inverse parallel thyristor pair. Analyses of the first fundamental component of the Fourier series of the load current from the laboratory test results are present. Other dependent variable such as distortion factor, displacement factor and
displacement angle were examined using a firing angle (?) or 300 for the thyristors. The thyristor used was TIC 106M, with current rating (IT(ava) Max). of 3.3A and a gating voltage (VGT) of 1.2V. the results obtained were used to plot curves of normalized fundamental harmonic load current ( ILnorm) Versus ?, an output normalized current (ILnorm)
versus ? , the distortion factor versus ?, the displacement factor versus ?, and the displacement angle versus ?. These analyses are intended to assist an industrial engineer to determine the appropriate angle to fire a thyristor, depending on the load current demand, in order to minimize power loss.
