IEEE-PEMC 2018 TUTORIAL PROPOSAL 1. TUTORIAL TITLE: Rectification Harmonics in Motor Drives: Modeling and Control 2. TUTORIAL ABSTRACT In modern industrial motor drive applications, low-cost, simple-structure, and high-reliability are the major concerns. Among various standardized front-end solutions, the diode rectifiers and/or siliconcontrolled rectifiers are still the most commonly employed rectification apparatus in adjustable speed drive systems. However, these line-commutated rectifiers introduce harmonics to the grid. In order to deal with the harmonic challenges, cost-effective solutions should be developed to comply with standard regulations. The emphasis of this seminar is systematically to give a complete and clear picture on the power electronics technologies in motor drive applications and views on future research opportunities. More importantly, recent research activities and advanced solutions in this research area for harmonic and low frequency EMI control will be presented. Specifically, this seminar covers harmonic requirements for motor drives, modeling of single-phase and three-phase based rectification systems and PFC technology for harmonic control, and multiple drive systems optimization under ideal and multitude grid faults conditions. 3. WHO SHOULD ATTEND This tutorial is intended for intermediate and advanced audiences in power electronics and its applications in motor drives. Researchers and engineers who seek for the basic knowledge for motor drive systems as well as ac/dc rectification technologies are also very welcome. 1
