Topic: Applications of Multilevel Converters to GridConnections and Motor Drives
Speaker: Hirofumi Akagi，Distinguished Professor Tokyo Institute of Technology
Time: 14:00, Thursday, Nov. 9th
Venue: Room 201, Electrical Engineering Building, Yuquan Campus
Abstract:
This talk presents cascaded multilevel converters and modular multilevel converters, or morestrictly, modular multilevel cascade converters in a broad sense. Special attention is paid to circuittopology and control strategy, along with their applications to grid connections and motor drivesystems. This speaker turns on a modular multilevel converter, or more strictly, a modularmultilevel double-star chopper-cell (DSCC) converter that attracts the most attention among thesix modular multilevel cascade converter family members. Finally, the speaker presents threedownscaled motor drive systems using two kinds of modular multilevel cascade converters.
