Harmonic Detection for Three-Phase Uncontrolled Rectifier Bridges Based on MATLAB SIMULINK

This research focuses on developing a novel harmonic detection method for three-phase uncontrolled rectifier bridges using MATLAB SIMULINK. The approach integrates digital signal processing techniques with power electronics principles to analyze current and voltage waveforms, enabling accurate detection and quantification of harmonic content. The implementation utilizes SIMULINK's power system toolbox for modeling the rectifier circuit and incorporates FFT (Fast Fourier Transform) algorithms for harmonic analysis through MATLAB scripting. Key functions include waveform sampling, harmonic spectrum calculation, and THD (Total Harmonic Distortion) measurement. The research outcomes will contribute to improving power system stability and efficiency while providing scientific basis for developing effective harmonic suppression strategies. The simulation model allows parameter tuning and real-time waveform monitoring to validate harmonic detection accuracy under various operating conditions.
