GaN power semiconductor devices have been the recent focus of intense development efforts due to the promising material properties of GaN for next-generation power electronics applications. For power switching and rectifying applications, the ruggedness in breakdown is a critical requirement as addition of snubber circuits reduce the performance and efficiency of the system. … [Read more...] about Expert View: Avalanche and Short Circuit Robustness of Vertical GaN FET

Expert View: Achieving Higher Power Density With Good-Old Si MOSFETs
In 1984 I had the honor of traveling around Europe with the great Rudy Severns on a new technology teaching tour for Siliconix. I was a young applications engineer and the new technology then was the silicon power MOSFET. Engineers were using bipolar transistors in their switching power supplies, and Rudy in his “Advanced Power MOSFET Seminar” pointed out the many advantages of … [Read more...] about Expert View: Achieving Higher Power Density With Good-Old Si MOSFETs
Expert View: GaN Outperforms Silicon, Enters Mainstream
How does one define ‘main- stream’? In the case of gallium nitride (GaN) power semiconductor technology, we believe that since you can now buy a sleek, 65 W mobile charger using GaN for under $25 on Amazon, it is reasonable to assume that it has been fully accepted by the consumer markets, which—almost by definition—makes it a mainstream product. For more about this … [Read more...] about Expert View: GaN Outperforms Silicon, Enters Mainstream
Expert View: Derating the 5G Network
The massive resources required to deploy the 5G network necessitate a payback period for those financing it to recover their investment in a way that will sufficiently motivate the investment to be made in the first place. While this is obvious, how to accurately calculate this can be anything but. This is a very high-stakes game of risk management, which is exceedingly … [Read more...] about Expert View: Derating the 5G Network
Expert View: The Time for Software Defined Power Is Now
Reports on software defined power and its impact on current and future energy markets, data centers, new autonomous technologies, and computing power needs. The infrastructure is dominated by hardware and suppliers that are focused on devices that solve pinpointed problems—smaller, cheaper, and more efficient are typically the leading “values” of the solutions. That is what … [Read more...] about Expert View: The Time for Software Defined Power Is Now
