Design and Investigation of Solar PV-Fed PMSM Motor Drive

This paper presents a constant-speed Permanent Magnet Synchronous motor (PMSM) drive system fed by solar PV. The Speed is almost constant throughout the period. The presented scheme contains a solar panel, boost converter, three-phase inverter, and three-phase PMSM Motor. The control scheme includes Perturb and Observe algorithm for maximum power point tracking (MPPT) and an improved modified space vector modulation (IMSVM) controller for the three-phase inverter. Perturb and observe algorithm is implemented to extract the most amount of power from PV panels and IMSVM is used to control voltage for the three-phase inverter. The IMSVM has simple usage, has fewer harmonic contents, requires fewer computational calculations, has low switching losses, and most efficient technique. The MPPT algorithm is easy to practice, proficient, and adopted widely in commercial industries. PMSM motor is widely used in EVs water pumping, and other industrial applications. The proposed scheme has been simulated and results have been verified in MATLAB/Simulink environment and analyzed its performance characteristics.
