SIMULINK Model of BUCK Circuit for Small-Scale Wind Power Systems with MPPT Implementation

In small-scale wind power systems, the BUCK converter serves as a fundamental circuit topology for power conversion from wind energy to electrical energy. To achieve maximum power point tracking (MPPT), we employ MPPT algorithms to generate PWM signals that regulate the BUCK converter's output for optimal performance. The implementation typically involves perturbation and observation (P&O) or incremental conductance algorithms that continuously adjust the duty cycle based on power measurements. Our SIMULINK model integrates both the BUCK circuit simulation and MPP modeling components, interfacing them with the MPPT control algorithm through PWM signal generation blocks. This integrated approach enables comprehensive system optimization through real-time simulation of power conversion efficiency, voltage regulation, and dynamic response characteristics. The model architecture includes power electronics components (MOSFETs, diodes, inductors, capacitors), measurement blocks for voltage/current sensing, and MATLAB function blocks implementing the MPPT algorithm logic. This simulation framework significantly enhances small-scale wind system efficiency by minimizing energy waste and reducing environmental impact through optimized power extraction from wind resources.
