Abstract: This present paper deal with the power quality improvement using a Zeta ac-dc boost converter in the mid-point converter based Switched Reluctance Motor drive (SRM).Using a simple bridge rectifier the mid-point converter based SRM drive shows low power factor at ac mains and produces very high harmonics content. The proposed Zeta ac-dc boost converter in continuous conduction mode (CCM) with mid-point converter fed SRM drive which helps to improves the input power factor, reduces total harmonic distortion of ac mains current , provides constant dc link voltage and balanced capacitor voltages for static operation. The SRM drive with input Zeta converter is modeled and the performance is simulated in MATLAB environment for 230V and 50Hz. Here the Zeta converter performance is compared with a conventional bridge topology for the SRM drive.
