Abstract

In this paper, a simple technique for teaching undergraduate power system harmonics analysis is developed to model nonlinear load generated harmonics in a single-phase variable-speed DC machine drive (VSD). The proposed technique employs an equivalent circuit principle to model the effect of dynamic non-linear load generated harmonics. A time-domain computer simulation model based on the trapezoidal method of integration is used to calculate the load current and the source line distortion produced by a converter in VSD.
