Three-Level Simulation Files

Three-level simulation files serve as essential modeling tools in power electronics, primarily used for analyzing operational characteristics of multi-level inverters, converters, and related topologies. Developed on the MATLAB 2011b platform, these simulation files enable engineers to rapidly validate circuit designs, optimize PWM control strategies, and predict system performance under real-world operating conditions. The implementation typically involves MATLAB/Simulink models with customizable blocks for circuit components and control algorithms.

Compared to traditional two-level topologies, three-level structures demonstrate significant advantages in output waveform quality, switching losses, and electromagnetic interference. These simulation files commonly incorporate core modules such as carrier modulation strategies (e.g., SPWM, SVPWM), level switching logic, dead-time compensation, and closed-loop control algorithms like voltage/current dual-loop control. The code architecture often features modular design with configurable parameters for PWM generation and switching state management.

Since these files may involve internal corporate simulation data sharing, intellectual property protection must be considered. It's recommended to perform desensitization processing (e.g., removing sensitive parameters or specific process details) before technical exchanges. These resources provide valuable references for researchers and engineers studying multi-level technologies, particularly suitable for comparing harmonic characteristics of different modulation algorithms or investigating midpoint potential balancing issues through parameterized simulation studies.
