X. Levels

Understand and analyze the potential advantages of series/parallel connection and understand the difficulties of implementation. Manage degrees of freedom and constraints in multilevel converters.

Study methods of controlling static converters by Pulse Width Modulation (PWM): principles and implementation. Apply to voltage converters. Extend to multilevel converters. Analyze using the 2N vector approach, then multilevel.
