Abstract

This paper proposes a single pulse operation SRM converter topology based on the basic buck-fronted topology and the modified C-dump topology. Using only (n+1) power switches, this topology can achieve full single pulse operation, thereby reducing switching losses and acoustic noise. It also achieves a greater de-magnetizing voltage compared to the basic buck-fronted topology, without having to increase the DC source voltage. The converter is more robust as its dump capacitor stops being charged if the chopper switch fails. The principle of operation, modes of operation and transient simulation results are presented
