My guess on why this took so long is that these types of collaborations tend to form after some parties have taken a bit of a lead in the industry. That's very appropriate, I think. But before that, it's more of a free-for-all. The downside is that others may be reluctant to join such a collaboration, leading to secondary or tertiary alliances, which can be counterproductive.
I sincerely hope this effort succeeds in the spirit of advancing the art of power devices for electric vehicles and other applications. This made me wonder: What other initiatives like this would help that cause?
I suspect that the very nature of this "emerging market" has helped build such an industry association as PDEA.
But of course, that "emerging market" thing could be also a double-edge sword. Some companies may see that it's more important to establish their own competitive advantage first, before joining such an industry-wide initiative.
That said, with a big customer like Toyota (who wouldn't want to work with them?), and a testing equipment company like Advantest (who is more or less in a neutral position), the PDEA may be off to a good start. We will keep you posted.
The venerable 12V electrical system is slowly being supplanted by higher-voltage architectures, especially in hybrids and electric cars. Some of those new systems operate at voltages as high as 450V and 600V, enabling the vehicles to run starter-generators, while minimizing the windings in the electric motors that drive the wheels.
This, in a way, nicrely sums up why we need better power devices that meet the higher-voltage higher current requirements.
Germans and Europeans are also good at High Voltage High Current devices and technology. They may have different way to accomplish solutions. Will world have two power device standards - at least for first few years? And will American vendors have third and final converging standard?
@Junko: I suggest Japanese and Germans develops initial draft of two independent novel way of this power initiative. After 06 or 12 months they sholud have joint discussion group to take best of these two efforts and make a new standard. This way consumer will get better future technology.
While Japan and Germany have in past made many high power high voltage devices (the BiPolar era) and they now have III-V experience with making LED's, but there seems to be a reliability issue with high voltage high current GaN except on SiC. Am I wrong about that? Cree stock has skyrocketed this year..the kings of SiC.
