A Hybrid Power Conversion System Using Three-Phase Single-Stage DC–AC Converter

This research article emphasizes about incremental conductance method of tracking maximum power point and sliding variable structure control implemented for three-phase single-stage DC–AC converter for hybrid electric power generation. The variations in PV array have been reduced by MPPT converter and tied along with wind voltage to the DC bus. At a single stage, the three-phase voltage of 415 V, 50 Hz, has been obtained by using DC–AC converters. The sliding mode control used aims at reducing the power stages and also produces constant output voltage. In the proposed system, the signal harmonic components are found to be very low. The system is developed in MATLAB–Simulink environment, and the outputs have also been presented.
