TORQUE RIPPLE MINIMIZATION OF PV BASED SRM DRIVE

Abstract

The switched reluctance motor drive is the recent choice for industrial applications due to its unique features like double salient pole motor without winding, permanent magnet and commutator in rotor. Solar photovoltaic based water pumping system using AC and DC motor is common but SRM drive is more favourable in terms of cost, reliability, robustness in nature. The primary drawback of SRM drive is higher torque ripple which makes heavy noise and vibration. This study discussed about the various kind of converters like C-dump, R-dump, Asymmetric and Mid-point converter fed SRM drive then chosen the efficient one to reduce the ripple. Incremental Conductance maximum power point tracking(IC-MPPT) algorithm is established for smooth starting of the SRM drive. The DC-DC converter is successfully eliminated from the present system and connected the SPV array directly to the best converter fed SRM drive, which is more compact, economical with good efficiency. Moreover, the study showed the design of the SRM using Ansys Maxwell. The converters and SPV array are modelled in MATLAB software then develop a prototype of the proposed system also to examine its validity.
