Analysis and modeling of different types of converter in switched reluctance motor for reducing the torque ripple

Switched reluctance motor (SRM) has developed into a competitive choice for many applications of electric machine drive systems in recent times due to its relative simple construction and robustness. The advantages of SR motors are highly reliable, good performance and reduces the maintenance. The absence of windings in rotor and permanent magnets gives possibility to achieve very high speeds (above 10000 rpm) and turned SRM into perfect solution for operation in hard conditions like presence of vibrations or impact. Such simple mechanical structure greatly reduces its price. This paper presents detailed analysis, and modeling of six dfferent type of converters used in with three phase switched reluctance motor (SRM). These converters are Asymmetric, Bifilar, Auxiliary, High Demagnetization-dump, C-dump type. These converters are simulated by MATLAB/SIMULINK package. This paper introduces, why the asymmetric bridge converter is the best one for Switched reluctance motor in high speed with torque ripple reduction.
