Solar PV array buck-boost converter fed single phase induction motor drives for water pumping

In this paper a single phase water pumping IM drive is consider which is fed by SPV (Solar Photovoltaic) array system which buck-boost dc-dc converter. In this paper we proposed a three stage power conversion consist of buck-boost converter and VSI. In first step the main requirement is to extract maximum power from PV and it is done by MPPT control. In this paper INC MPPT control is used which gives the duty ratio which control the dc-dc converter. For better performance of IM, V/F controlled VSI is employed for DC-AC conversion. The V/F control generate required magnitude and frequency for SPWM which control VSI. The proposed model is modelled and simulated in Matlab/Simulink platform and result shows effectiveness of proposed system.
