Catalog Description:

The course introduces students to advanced power electronics converters dealing with ac voltage. The power electronics topologies considered in this course are sorted into two groups: multilevel configurations and back-to-back converters. The multilevel configurations presented are a) neutral-point-clamped, b) cascade, c) flying capacitor, and d) non-conventional multilevel configurations. The back-to-back converters presented are a) three-phase to three- phase, b) single-phase to three-phase, c) single-phase to single-phase ac-dc-ac converters. A new methodology will be employed to present comprehensively multilevel and back-to-back converters topologies. The main applications of those converters are in renewable energy systems, active power filters, energy efficiency devices and motor drive systems. Furthermore, this course introduces a new method to present power electronics converters called Power Blocks Geometry (PBG). Such methods focus on how the main power converters were conceived by following a simple yet effective teaching process. Furthermore, this course offers a comprehensive set of simulation results to help understand the circuits presented as well as applications for those converters.
