GaN’s Evolution from Science Project to Mainstream Power Conductor

GaN’s Evolution from Science Project to Mainstream Power Conductor

Power-conversion technologies are experiencing the first tectonic shift since the move from bipolar to MOS. That shift, of course, is due to the viral adoption of wide-bandgap power devices. At this point, GaN is more than a specialty technology; it is a broad-scale replacement for silicon MOSFETs in applications ranging from 30 V up to 650 V — a multibillion-dollar market.

Podcast: GaN Devices for Space Applications

Podcast: GaN Devices for Space Applications

GaN power devices should be the ideal choice for power conversion applications in space because they are more robust than rad hard MOSFETs when exposed to various forms of radiation. The electrical and thermal performance of GaN has also demonstrated superior operation in a space environment. In this podcast, Bel Lazar, Chief Executive Officer of EPC Space, will analyze the importance of GaN for the space industry. In addition to his role as CEO of EPC Space, Bel currently serves as COO of Efficient Power Conversion (EPC).

Dispelling a Myth – GaN and Motor Drivers

Dispelling a Myth – GaN and Motor Drivers

There is a commonly held belief in the industry that GaN devices are wasted on inverters for electric motors. After all, if the performance of the system is restricted by the use of a 20KHz PWM, then there can be little benefit in using a material that gains the majority of its advantages from faster switching speeds. However, according to Marco Palma, Director of Motor Drives Systems and Applications at EPC, there are some ways that GaN can still prove effective in that role.

GaN vs. Silicon Smackdown

GaN vs. Silicon Smackdown

One way to tell when a new technology has passed the tipping point of adoption is by the voices advocating the status quo. The more conservative voices tend to cite older information that, given the fast change of trajectory that occurs at a tipping point, can lead to poor decisions for new designs. In the world of GaN power devices the tipping point occurred in the past two years when the rate of new GaN-based designs started to double year-on-year, and the legacy MOSFET designs started to face critical supply shortages due to their finely tuned, but less flexible supply chains. GaN devices, on the other hand, have remained in stock at most major distributors due to their relatively new and flexible supply chains utilizing older silicon foundries, but affording these foundries a new and vibrant future. In this article we will address some of the common misconceptions still showing up in articles and at conferences, usually presented by advocates of the status quo.

Wide-bandgap (WBG) Components Build a Green World that is Highly Efficient and Saving Energy

Wide-bandgap (WBG) Components Build a Green World that is Highly Efficient and Saving Energy

The mainstream materials for wide-bandgap (WBG) semiconductor power components are silicon carbide (SiC) and gallium nitride (GaN). They become various power system applications' most-preferred devices today with the rising awareness of energy conservation and sustainability. This was the first time Tech Taipei 2022 Conference used WBG as its theme. Speakers from key players in the industry were invited from design, manufacturing and testing fields to share with over 400 participants at the conference their latest technology and application trends.

Roadblocks to GaN Adoption in Power Systems

Roadblocks to GaN Adoption in Power Systems

In this article, the most common reasons for some customers to be slower in their embracing what is clearly a displacement technology for their older silicon-based power MOSFETs will be discussed. Without going into the detailed statistics, a list of reasons, in order of frequency is derived. This list is based upon the understanding that some applications will place higher emphasis than others on certain characteristics of GaN. Our discussion is limited to devices rated at less than 400 V, as that is the application focus for Efficient Power Conversion (EPC) FET and IC products.

GaN Devices for Smaller, Lighter, Smoother Motor Drives

GaN Devices for Smaller, Lighter, Smoother Motor Drives

Today, the permanent magnet motor, also known as DC brushless motor (BLDC), is widely used and offers higher torque capability per cubic inch and higher dynamics when compared to other motors. So far, silicon-based power devices have been dominant in the inverter electronics, but today their performance is nearing their theoretical limits. There is an increasing need for higher power density. Gallium nitride (GaN) transistors and ICs have the best attributes to satisfy these needs.
