SPWM Inverter Simulation Source File with Harmonic Injection Technique

This file contains a complete SPWM inverter simulation source code that executes directly in MATLAB 7.1. The implementation features a PWM Generator designed to accept external modulation signals, with intelligent third harmonic injection integrated into the modulation algorithm. This approach significantly suppresses output harmonics while enhancing DC power supply utilization through optimized voltage modulation techniques.

To further improve SPWM inverter performance, several enhancement strategies can be implemented in the code architecture. First, expanding the modulation signal's frequency spectrum through algorithm adjustments can increase the inverter's output frequency range. Second, optimizing modulation signal amplitude and phase parameters enables more precise voltage waveform control using mathematical modeling techniques. Additionally, implementing advanced filtering algorithms or circuit configurations can further reduce output harmonics. Furthermore, exploring sophisticated modulation techniques such as multi-level PWM or hybrid modulation strategies through code modifications can significantly enhance inverter efficiency and performance metrics.

By implementing these algorithmic improvements, the SPWM inverter can achieve greater stability and reliability in practical applications, generate more accurate output voltage waveforms, reduce harmonic distortion, and improve energy utilization efficiency. These technical enhancements provide valuable implementation guidance for research and practical engineering applications!
