Abstract

This paper presents detailed analysis, and operation of Asymmetric Half Bridge (AHB) converter topology and shared switch converter topology for 4-phase Switched Reluctance Motor (SRM) drives. Compared to an asymmetric half bridge converter, shared switch converter reduces the number of switches and diodes. Simulation results show that both topologies give the same results of phases flux, phases current, torque electric, and speed. However, some switches in shared switch converter controlled more than one phase. So, the number of switching at operation speed condition is twice more than other switches on asymmetric half bridge or shared switch converter. The simulation results are made by MATLAB/SIMULINK.
