When a new technology is introduced, it is not reasonable to think that engineers will intuitively know how to effectively and efficiently take advantage of the performance enhancements that the new technology offers – there is always a learning curve. This is being borne out in the case of the rapidly emerging technology of high performance gallium nitride transistors.

GaN FET technology was made available to the general power conversion engineering community in mid-2010 when Efficient Power Conversion (EPC) introduced the industry’s first commercially available GaN transistor. Since that time, EPC has continued on two parallel paths – one to expand their portfolio of products and the other to share what it learns about the use of the technology with power conversion systems design engineers. One of these educational efforts has been to work with the editors of Power Electronics magazine and publish a bi-monthly series of articles on the characteristics of GaN technology and its applications.

This series is entitled eGaN FET -- Power Silicon Shoot Out. Articles in the series took on both basic issues and specific applications using gallium nitride components. It is timely to make a quick review of the sixteen articles to make certain that we have accomplished the goal of assisting engineers in climbing the learning curve. This retrospective look will give us insight into what further topics and studies are needed to advance the adoption of GaN technology, the need to learn is never finished.

For a power system designer who has worked with a power MOSFET, upgrading to an enhancement mode GaN transistor is straightforward. The basic operating characteristics are quite similar and yet there are a few characteristics that need to be considered in an efficient design in order to extract the maximum benefit from this new generation device.

EPC9107 demonstrates size reduction and efficiency enhancement for power conversion achieved using high frequency switching eGaN power transistors

EL SEGUNDO, Calif.—June, 2013 — Efficient Power Conversion Corporation (EPC) introduces the EPC9107, a fully functional buck power conversion demonstration circuit.  This board is a 9 V-28 V input to 3.3 V, 15 A maximum output current, 1MHz buck converter.  It uses the EPC2015< eGaN FET in conjunction with the LM5113 100V half-bridge gate driver from Texas Instruments. The EPC9107 demonstrates the reduced size and performance capabilities of high switching frequency eGaN FETs when coupled with this dedicated eGaN driver.

The EPC9107 demonstration board is 3” square and contains a fully closed-loop buck converter with optimized control loop. The complete power stage including eGaN FETs, driver, inductor and input/output caps is in an ultra compact 0.5” x 0.5” layout to showcase the performance that can be achieved using the eGaN FETs with the LM5113 eGaN driver.

Since gallium nitride (GaN) based power devices have a vast potential to grow in usage, this market opportunity continues to attract more new suppliers. As a result, the list of manufacturers of GaN technology based power devices is steadily expanding. How2Power June, 2013 More ...

Packaging has its downsides: It increases the footprint and the price of a power MOSFET, while degrading its performance through unwanted increases in resistance and inductance. The best solution is to ditch the package, a step that allows GaN HEMTs to be cost-competitive with silicon incumbents, argues Alex Lidow from Efficient Power Conversion Corporation.

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.

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.
