The reason eGaN FETs (and now ICs) are used in all the LiDAR systems for autonomous cars, and now autonomous race cars, is that they enable much higher resolution (due to extremely short laser pulses), faster image speed (due to short laser pulses), and the ability to see greater distances with high accuracy (due to fast laser pulses at very high current).

EL SEGUNDO, Calif. — June 22, 2018 -- Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN^®) power FETs and ICs, will meet with design engineers in power management in Shanghai, China, for knowledge exchanges on solutions using a synchronous FET Class E rectifier for over 30 W highly-resonant wireless power receivers, and a kilowatt laser driver with 120 A, sub-10 nanosecond pulses in < 3 cm² using eGaN FET.

Meet EPC experts on power management at PCIM Asia Exhibition and Conference on June 26th, 2018 (Tuesday) at 10 a.m. – 10.50 a.m. at Exhibition Hall No. 2, 1/F of Shanghai World Expo Exhibition and Convention Center, 1099 Guozhan Road, Shanghai, China.

For LiDAR systems to meet ever-higher performance specs, they must perform fast switching of high-current pulses, which is where a gallium-nitride power switch can step in to help.

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in the ecosystem of power electronics that support GaN-based designs.

As GaN-on-Si becomes more common in DC-DC converter designs, questions often arise from experienced designers about the impact of the unique characteristics of GaN transistors when used as synchronous rectifiers (SRs). In particular, the third quadrant off-state characteristics, better known as “body diode” conduction in Si MOSFETs, which is activated during converter dead-time, is of interest. For this article, the focus will be on the similarities and differences of Si MOSFETs and eGaN^® FETs when operated as a “body diode” and outline their relative advantages and disadvantages.

EL SEGUNDO, Calif. — June 2018 — jjPLUS Corporation, a design manufacturer of advanced wireless communication and wireless power embedded solution company, will demonstrate the next-generation magnetic resonance wireless power transfer (WPT) technology at InnoVEX 2018 in Taipei. Joining jjPLUS will be its technology partner − Efficient Power Conversion Corporation (EPC). The demonstration units will be located in TWTC Hall 3, booth no. G0309a on June 6 – 8. Both jjPLUS and EPC participated in the AirFuel working committees and in the AirFuel Developers Forum in March 2018.

Superior characteristics of eGaN^® FETs and integrated circuits, such as low output capacitance, low input capacitance, low parasitic inductances, and small size make them ideal for increasing efficiency in highly resonant, AirFuel™ wireless power transfer systems.

EL SEGUNDO, Calif.— May 2018 — Efficient Power Conversion Corporation (EPC) today announces the availability of a complete class 4 wireless power kit, the EPC9129. The system can transmit up to 33 W while operating at 6.78 MHz (the lowest ISM band). The kit comes complete with two receivers, each with a regulated output − one capable of 5 W capable and a second capable of delivering 27 W at 19 V.

Spirit Electronics now provides distribution support to assist customers in adopting eGaN^® FETs and ICs for leading-edge power conversion systems in the defense and aerospace market.

EL SEGUNDO, Calif.— May 2018 — To support its accelerating growth in the defense and aerospace markets, Efficient Power Conversion Corporation (EPC) is proud to announce the appointment of Spirit Electronics as a distribution partner focusing on these key market segments.  Spirit Electronics, in operation since 1979 and located in Phoenix, Arizona and Irvine, California, supplies products and services to the Department of Defense, aerospace, and telecommunication industries.  

Efficient Power Conversion (EPC) will exhibit live demonstrations at PCIM Europe 2018 showing how GaN technology’s superior performance is transforming power delivery for entire industries including computing, communications, and automotive.

EL SEGUNDO, Calif. — May 2018 — The EPC team will be delivering five technical presentations on gallium nitride (GaN) technology and applications at PCIM Europe 2018 in Nuremberg, Germany from June 5^th through the 7^th. In addition, in Hall 7, Stand 539, the company will exhibit its latest eGaN^® FETs and ICs in customers’ end products that are enabled by eGaN technology.

The increase in switching speed offered by GaN transistors requires good measurement technology, as well as good techniques to capture important details of high-speed waveforms. This article focuses on how to leverage the measurement equipment for the user’s requirement and measurement techniques to accurately evaluate high performance GaN transistors. The article also evaluates high bandwidth differential probes for use with non-ground-referenced waveforms.
