RAP Sessions

The APEC 2019 Rap Sessions will have several exciting and contentious topics lined up. Rap Sessions allow for exciting dialogue amongst attendees and presenters. Admission to all Rap Sessions is free with an Exhibits Only Registration.

Rap Session 1: When will WBG have significant volume? Is the system benefit worth the cost?  Is WBG reliable?

Tuesday, March 19 | 5:00 p.m. - 6:30 p.m. | Ballroom D

Moderator: Alix Paultre, Smartalix


  • Sandeep Bala,  ABB Corporate Research Raleigh
  • Tim McDonald, Chairman of JEDEC JC 70.1 
  • Alex Lidow, EPC
  • Jim Witham , GaN Systems 
  • Chris Dries,  United SiC
  • Filippo DiGiovanni, STMicroelectronics


Now that the availability and performance of wide-bandgap semiconductors in the marketplace has been established, the focus is shifting from promise to reality. What application spaces face the most disruption? What opportunities are presenting themselves? The panel for this rap session includes manufacturers selling Silicon Carbide (SiC) and Gallium Nitride (GaN) components, and the companies designing their current and future products with them. What is the current state of the wide-bandgap industry? Come participate in our rap session and find out!

Rap Session 2: Power supply on chip (Pwr SOC) vs. Power supply in package  (Pwr SIP)  vs discrete.  What is the future?

Tuesday, March 19 | 5:00 p.m. - 6:30 p.m. | Ballroom C

Moderator: Indumini Ranmuthu, Texas Instruments


  • Hanh-Phuc Le, PwrSoC technical program chair (UC Boulder)
  • Charlie Sullivan,  Dartmouth University
  • Koduri, Sreenivasan, Texas Instruments Fellow
  • Mohamed Jatlaoui , Murata
  • James Doyle, Dialog semiconductor
  • Martin, Haug, Würth Elektronik 


There is significant trend in the industry towards higher power density and integration in power supplies. This integration has given rise to complex issues such as building complete power supplies on chip, 3D packaging for power supply in single package, highly miniaturized passives,  thermal density and efficiency.  The panelists for this session includes experts from actual design of power supply on chip, 3D packaging, design of miniaturized inductors and capacitors. Come participate, ask your questions from the experts and find out the state of the art!


Rap Session 3: High Technology Holdup- Is magnetics really the constraint or are magnetics waiting for everything else to catch up?

Tuesday, March 19 | 5:00 p.m. - 6:30 p.m. | Ballroom B

Moderator: Kevin Parmenter, Advanced Energy


  • Ray Ridley, Ridely Engineering
  • Steve Tom, Texas Instruments   
  • Dan Jitaru, Rompower
  • Eric Persson, Infineon 
  • George Slama, Wurth
  • Larry Spaziani, GaN systems 


Enormous efforts are being made to uncover new semiconductor technologies and circuit topologies to supply the ever-changing demands of modern electronics. At each step, magnetics seem to be there for those companies that understand how to design them properly.  We will debate this and explore the constraints.   Come and join this discussion about what we will need to be prepared for the next generation of power electronics.
