Abstract and Speaker info below:

Energy conversion is under the spotlight and the technology inside is moving faster than ever:
SiC was the 1st innovative material, outperforming Silicon in all domains when used in power switches, but it has taken more than 10 years for the first switches to be released.   Most of the big manufacturers are involved in SiC development (Infineon, ST Microelectronics, Rohm…) and their unique strategies can be the game changer.   For example, Fairchild gave up all developments 3 years ago, and then this year to prepare a comeback in the SiC business purchased TranSiC.
In addition another material challenger is now present, GaN, widely used in LED’s, has emerged in power electronics applications. It has its pros and cons but it is very attractive for many applications (MV power supplies, EV/HEV). Several start-ups are developing solutions (EPC, Transphorm, Powdec) as well as bigger players like International Rectifier.
On the other side, Silicon is still here. Improvements are made on MOSFETs and IGBTs at a competitive cost. Super Junction structure is eating market shares with CoolMOS® or MDmesh® products and four players revealed their portfolio in the last 18 months (Fuji electric, Alpha&Omega Semiconductor, Vishay and Renesas).
This complicated landscape brings lots of questions:

  • Where are these technologies positioned?
    • Which applications could they target? Which will they penetrate in the future?
    • How are they positioned one versus the other?
  • What are manufacturers’ strategies and roadmaps?
  • What will be the impact in system design, BoM and manufacturing?

In this webcast we will provide key facts, assumptions and market metrics and forecasts  to answer these questions..  Obviously the supply chain is critical to the entire market review, while the system manufacturers will want to understand the impact of these new devices , and in turn the device and equipment manufacturer will want to understand their options to provide the right solutions, at the right time.
