Abstract

In modified single-pulse operated switched reluctance generator (SRG), phase conduction interval need not be a complete electrical cycle. The phase conduction interval changes with control angles. This gives rise to multiple possibilities of phase overlap in modified single-pulse mode. This article presents a method to systematically identify all the possibilities of phase overlap for a given pair of control angles. It is found that there are seven possibilities of phase overlap in modified single-pulse mode. The paper derives the inequality conditions to identify these cases. The paper also determines the switching function for each possibility of phase overlap. Utilizing the switching function, the instantaneous dc-bus current is also expressed in terms of phase current. All seven possibilities of phase overlap and estimated instantaneous dc-bus current are validated through experiments on a 4-kW 4-phase SRG. © 2024 IEEE.
