Solar PV-based VFD fed permanent magnet synchronous motor for pumping system

Abstract

This paper determines the incorporation of photovoltaic source and battery with a PMSM motor fed with a centrifugal pump based on conventional Direct Torque Control technique (DTC). For the boosting of solar output, interleaved DC-DC converter with fuzzy logic-based MPPT control is studied and in order to convert the DC output of converter for the required form of motor input, three-phase inverter has been taken. With the help of a bi-directional converter, regulation of battery is carried out which depends on load and source. Output results of motor as well as pump are obtained using MATLAB Simulink environment.
