Abstract
This paper presents an EMTDC simulation of commutation spikes in a synchronous generator voltage waveform when supplying rectifier loads. The effect of the thyristor snubber circuit on the spikes is investigated. In the simulation, an artificial value of the snubber resistance is required to give a more accurate decay time for the spike oscillation without losing the fundamental frequency characteristics of the voltage waveforms. The results obtained from two rectifiers with different snubber circuits are presented. The analysis in this paper should assist all those trying to simulate switching transients in lightly damped RLC circuits using time stepping techniques.
