How to measure the world's fastest power switch

Gallium Nitride (GaN) FETS are poised to replace silicon power devices in voltage regulators and DC-DC power supplies. Their switching speeds are significantly faster and their RDS(on) is lower than silicon MOSFETS. That can lead to higher power efficiency power sources, which is good for all of us. If you're designing power circuits with GaN devices, you need a grasp of the device's switching speed.

Power GaN Market - 80% ANNUAL GROWTH FROM 2016-2020!

Overall, 2020 could see an estimated device market size of almost $600M, leading to approximately 580,000 x 6” wafers to be processed. Ramp-up will be quite impressive starting in 2016, at an estimated 80% CAGR through 2020, based upon a scenario where EV/HEV begins adopting GaN in 2018-2019. The power supply/PFC segment will dominate the business from 2015-2018, ultimately representing 50% of device sales. At that point, automotive will then catch-up.

Yole: Power To Dominate GaN-On-Silicon Market

Yole Développement is releasing, this week, the "GaN-on-Si Substrate Technology and Market for LED and Power Electronics" report. Analysts believe that GaN-on-silicon technology will be widely adopted by power electronics applications. The power electronics market addresses applications such as AC to DC or DC to AC conversion, which is always associated with substantial energy losses that increase with higher power and operating frequencies. Incumbent silicon based technology is reaching its limit and it is difficult to meet higher requirements.

Efficient Power Conversion Corporation (EPC) Market Leading eGaN® Power Transistors Recognized as EDN Magazine Hot 100 Product for 2013

EPC8000 family of gallium nitride FETs give power systems and RF designers access to high performance GaN power transistors capable of amplification into the low GHz range, enabling innovative designs not achievable with silicon.

EL SEGUNDO, Calif. — December 2013 — Efficient Power Conversion Corporation, ( the leader in enhancement mode gallium nitride FET technology, announces today that its EPC8000 family of high frequency eGaN FETs has been recognized with inclusion in the EDN list of 100 Hot Products for 2013.

“We are very excited that EDN, an industry-leading magazine, has recognized our innovative new family of eGaN FETs. These devices take EPC and gallium nitride transistor technology to a level of performance that enables applications that were previously beyond the capability of silicon MOSFETs. The EPC8000 eGaN FETs blur the line between power and RF transistor technology,” said Alex Lidow, EPC’s co-founder and CEO.

These third generation devices have cut new ground for power transistors with switching transition speeds in the sub nano-second range. They are capable of hard switching applications even beyond the 10MHz for which they were designed. These products exhibit very good small signal RF performance with high gain well into the low GHz range, making them a competitive choice for RF applications.

Examples of applications benefiting from the low power, compact, high frequency EPC8000 family of devices include hard-switching power converters operating in the multi-megahertz range, envelope tracking in RF power amplifiers using EPC8005, highly resonant wireless power transfer systems for wireless charging of mobile devices.

About EPC

EPC is the leader in enhancement mode gallium nitride based power management devices. EPC was the first to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in applications such as DC-DC converters, wireless power transfer, envelope tracking, RF transmission, solar micro inverters, remote sensing technology (LiDAR), and Class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs.

Exploring gallium nitride technology

It has been three years since the commercialization of gallium nitride (GaN) devices as MOSFET replacements in a commercial DC-DC application. With the emergence of GaN devices, coupled with now attainable applications previously not achievable with MOSFET-based FETs, a favorable stage has been set for GaN-device developers to release emerging application potential largely unimagined and untapped.

Paultre on Power - Power GaN

Author: By Alix Paultre, Editorial Director, PSD
Date: 3/12/2013

In this podcast, we talk to Alex Lidow of Efficient Power Conversion (EPC) about GaN devices and their impact on the power industry. EPC is a leader in enhancement-mode Gallium Nitride based power management devices. EPC was the first to introduce enhancement-mode Gallium-Nitride-on-Silicon (eGaN®) FETs as power MOSFET replacements in applications such as point-of-load converters, Power over Ethernet (PoE), server and computer DC-DC converters, LED lighting, cell phones, RF transmission, solar micro-inverters, and class-D audio amplifiers with device performance many times greater than silicon power MOSFETs.

GaN-on-Si Based FETs Foster New Applications

Although, for the last few years, there has been a lot of talk about gallium nitride(GaN) based power transistors displacing the entrenched silicon MOSFETs, it might take some time before the emerging gallium nitride on silicon (GaN-on-Si) based power FETs enter the mainstream power conversion space. However, in the meantime, a handful of emerging applications are poised to tap the benefits of this promising power technology. Besides commercial availability with high reliability, there are a number of unique GaN characteristics that are fostering these new applications.

Are GaN Transistors Ready for Prime Time?

Gallium Nitride transistors have been available since Eudyna and Nitronex first introduced depletion-mode RF transistors in about 2005. Since then many new companies have entered the field with both RF transistors (e.g. RFMD, Triquint, Cree, Freescale, Integra, HRL, M/A-COM, and others), and transistors designed to replace power MOSFETs in power conversion applications (e.g. Transphorm, International Rectifier, GaN Systems, microGaN, and Efficient Power Conversion). This article discusses if this ground swell of activity mean that GaN transistors are ready to replace power MOSFETs, and, if so, why?

Huge Expectations for GaN Market Growth

The GaN power device industry has probably generated less than $2.5M revenues in 2011, as only 2 companies (IRF & EPC Corp.) are selling products on the open market. However, the overall GaN activity has seen extra revenues as R&D contracts, qualification tests and sampling for qualified customers was extremely buoyant.
