Design of Parallel Boost Converters for Renewable Energy Applications

To achieve effective electrical power conversion from both the photovoltaic (PV) system and the wind system, parallel-connected boost converters (PBC) are employed in this paper. A perturb and observe (P O) formula-based concentrated power opinion tracing (CPOT) controller operates the PV and wind-operated permanent magnet synchronous generator, providing the input supply to the proposed converter. With the help of the PBC, the direct current (DC) voltage is increased and converted into a single-phase, 230Vrms, 50Hz alternating current (AC) voltage in a single-stage operation. For this DC power to AC power conversion, the system attempts to synchronize two different power sources. The sliding variable configuration control (SVCC) method is used to control the proposed PBC to obtain a constant AC output voltage from variable DC input voltage sources. The recommended control method has been applied to maintain the output voltage constant through changing load conditions. The implemented technique increases the performance of the power transition system while reducing total harmonic distortion (THD). The entire system is structured using the MATLAB/Simulink environment, which is utilized to validate the results.
