Solar PV Fed SIDO Modified Buck-Boost Converter for SRM Driven Irrigation Pump

This paper provides a reliable solution for photovoltaic (PV) array fed irrigation pump system using switched reluctance motor (SRM). A PV fed single input dual output (SIDO) modified buck-boost converter is utilizes as a DC-DC power transformation stage between PV array and SRM-pump in proposed system. The power optimization of PV array and to provide soft-starting to SRM drive are the two major objectives of this converter. The continuous current through inductors of SIDO modified buck-boost converter helps to minimize the strain on its components and to enhance the conversion performance. The fundamental frequency switching of converter of SRM at line frequency minimizes the losses of the system and provides an opportunity to eliminate the sensors from the drive side. A self-start control algorithm is also introduced in the proposed system. The satisfactory steady-state and dynamic performances of the proposed system under variable environmental conditions show the superiority over the existing methods.
