A novel solar photo voltaic powered drive for the SRM for irrigation purposes using a partial resonant AC link DC to a DC boost converter

Abstract

In this study a novel drive for the Switched Reluctance Motor (SRM), powered by the solar photo voltaic (SPV) source, using a Partial Resonant Inverter (PRI) followed by a Doubler Rectifier (DR) for water pumping applications, has been proposed and validated. The PRI DR combination offers a large voltage gain that is required while using low-voltage SPV sources. The PRI increases the voltage level by resonance and also it exhibits zero voltage switching so that the switching losses are reduced. The proposed system also offers a sliding mode controller based on Maximum PowerPoint Tracking implemented in the PRI. The proposed system is a fixed torque variable speed application where the speed follows the solar irradiance. The proposed idea has been validated using simulations and experimental prototypes.
