PV with boost converter integrated three-level inverter fed PMSM drive for agricultural application

Abstract

Apprehension of inverter fed electric motors is made possible with the trends in power electronic technology. Permanent magnet synchronous motor (PMSM) is one motor replaced conventional electric motors with attractive features like compactness, lightweight and efficiency. This paper presents a PV (Photo-voltaic) fed PMSM drive system for water pumping application. Photo-voltaic system is one among the renewable sources available free from atmosphere which can generate electricity with ease. Output of PV is fed to a boost converter to generate required level of voltage to PMSM. Boost output is fed to a driving inverter to PMSM. Closed-loop boost converter feeding PMSM drive is analyzed. PMSM drive is a closed-loop system design to run at commanded speed. PV fed PMSM drive is validated with fixed speed and variable speed conditions.
