Spectrum Analysis Methods to the Two-Level Three-Phase Inverter
Aiming at the spectrum analysis, the classification of PWM strategies based on digital implementation for the three-phase inverter is given. Then the paper summaries the three spectrum analysis methods: theoretical expression, computer simulation and experiment. The structure and procedure of each method are discussed. Each method has advantages and disadvantages. The experiment and computer simulation can be used to analyze any PWM strategy. The theoretical expression is always used to analyze the deterministic strategies.
