A Hybrid Photovoltaic Power Converter System for Brushless DC Motor Operation and Control

Abstract

In the growth of renewable generation system, photovoltaic power generation plays an important role in present era. This paper presented an effective hybrid photovoltaic power generation using hybrid Cuk-Sepic power converter in integrated form. The space vector based neuro fuzzy sensor-less control is presented for brushless DC motor in variable load operation and control. Motor drawn supply power from hybrid photovoltaic generation. A fuzzy logic based MPPT scheme is applied for hybrid photovoltaic converter to extract maximum power. This presented configuration is used to an efficient power sharing of two- photovoltaic power generation to meet out power demand on load. The system was tested under high load brushless DC motor and dump load to verify hybrid power generation capacity. The circuit was tested using MATLAB/Simulink software to verify about this control and circuit configuration.
