Improved Modeling of a Multi-Level Inverter for TACS to Reduce Computational Time and Improve Accuracy

A modeling of a turbo air compressor system (TACS), with multi-level inverter for driving variable speed, combining an electrical model electric motor drive (EMDS) and mechanical compressor, is essential to accurately analyze dynamics characteristics. Compared the model, has short sampling time due high frequency switching operation numerous power semiconductors inside inverter. This causes problem increased computational dynamic characteristics analysis TACS. To solve this problem, conventional been proposed simplify semiconductors, however it low accuracy because does not consider pulse width modulation (PWM) operation. Therefore, paper proposes improved TACS reduce improve responses. In order verify reduced using simplified compared analyzed electronic circuit simulation software PSIM. Then, verified by comparison experimental results.
