"Capacitive Touch Design for Commodity Applications: Replace That Old Mechanical Switch!"  Topics to be covered include: 1.  Design related topics such as: how such a device operates, and the components that make up a capacitive touch system.  2.  User feedback, highlighting how simple things like driving multiple LEDs off of an unregulated supply, or leaving LED traces floating could negative effect system performance.  3.  System level testing to pass IEC 61000 series testing. Problems related to obtaining the coveted CE mark are centered on conducted susceptibility, or how the sensor interface reacts when introducing noise to the system. 4.  A Design checklist. Speaker(s): Chris Semanson, Agenda: Food and networking at 5:30, general chapter business at 6, talk beginning around 6:30, followed by discussion. Location: Bldg: UL University 12 Laboratory Drive Research Triangle Park, North Carolina 27709

We are excited to have Dr. Helen Li from Florida State University to give us a technical lecture on modulation and control strategies for DC/DC converter in MVDC systems. Presentation Title: Modulation, Control and Fault Protection of Current-fed Modular Bidirectional DC-DC Converter for Shipboard MVDC System Abstract: Current-fed bidirectional dc-dc converters have gained increasing popularity in a shipboard MVDC system due to their superior current control and fault performance.  This presentation will introduce different modulation methods of current-fed modular bidirectional converters applied in a shipboard MVDC system. The corresponding dynamic models as well as control system development for each modulation method will be presented and compared. Finally, the fault ride through operation of this type of converter will be also introduced.   Speaker(s): Dr. Helen Li, Agenda: 6:00 - 6:30 PM  Food and networking 6:30 - 7:30 PM  Lecture 7:30 - 8:00 PM  Q&A Location: Room: 1005 Bldg: EB1 911 Partners Way Raleigh, North Carolina 27606
