Title: "Application of LCL-Filters in Active Power Filter Systems"
This seminar discusses the design, control and implementation of an LCL-filter-based shunt active power filter (APF), which can effectively compensate for harmonic currents produced by nonlinear loads in a three-phase three-wire power system. With an LCL-filter added at its output, the proposed APF offers superior switching harmonic suppression using much reduced passive filtering elements. Its output currents thus have high slew rate for tracking the targeted reference closely. Smaller inductance of the LCL-filter also means smaller harmonic voltage drop across the passive output filter, which in turn minimizes the possibility of over-modulation, especially for cases where high modulation index is desired. These advantages, together with overall system stability, are guaranteed only through proper consideration of critical design and control issues, like the selection of LCL parameters, interactions between resonance damping and harmonic compensation, bandwidth design of the closed-loop system, and active damping implementation with fewer current sensors. These described design concerns, together with their generalized design procedure, are applied to an analytical example and verified by experimental results.
Yi Tang received the B.Eng degree in electrical engineering from Wuhan University, Wuhan, China, in 2007 and the M.Sc. and Ph.D degrees from the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, in 2008 and 2011, respectively.
During the summer of 2007, he was a visiting scholar with the Institute of Energy Technology, Aalborg University, Aalborg East, Denmark, where he worked on the control of grid-interfaced inverters and uninterruptible power supplies. Since July 2011, he has been with Infineon Technologies Singapore as a senior application engineer and responsible for cutting edge applications of power MOSFETs.
Dr. Tang has authored and coauthored more than 20 research papers. He has three U.S. patent applications and one German patent application.
