SIMULATION AND DESIGN OF BOOST CONVERTER FOR SOLAR PHOTOVOLTAIC SYSTEM

Abstract

Variable speed drives for PV-fed water pumping system (WPS) in rural areas prove highly promising for
economic and social growth. Being more economical without winding and permanent magnets on rotor,is emerging
as an attractive option in variable speed drives. Such a system demands for a suitable controller with simple and
reduced components. This paper presents the essence of PWM technique over single pulse mode (SPM) in PV-fed
WPS. Performance characteristics such as: torque ripple, phase peak current and DC-link current of the PWM
technique tested at various insolation levels are presented in this study. This simulation can be useful in
specifyingthe appropriateness of the MPPT algorithms for the different PV system applications. For this study,
SPVhas been used to build a look-up table based simulation model for SPV in Matlab/Simulink. The system is then
implemented using high parallel computing system.
