Efficient Power Conversion (EPC) will showcase the company’s latest enhancement-mode gallium nitride-based FETs and ICs demonstrating how GaN technology’s superior performance is transforming power delivery for automotive, computing, and robotics at the PCIM Europe 2021 Digital Days.

EL SEGUNDO, Calif.— April 2021 — The EPC team will be delivering two technical presentations, an educational tutorial, an exhibitor webinar, and participating in panel discussions on gallium nitride (GaN) technology and applications at the upcoming PCIM Europe 2021 Digital Days, May 3 – 7. In addition, the company will participate in the event’s virtual exhibition, showing its latest eGaN FETs and ICs in customers’ end products that are rapidly adopting eGaN^® technology.

The ultra-fast transition EPC2034C eGaN^® FETs used on the EPC9150 enables high current pulses up to 220 A and pulse widths under 3 ns, thus allowing a lidar system to see farther, faster, and better.

EL SEGUNDO, Calif.— March 2021 — Efficient Power Conversion  (EPC) announces the availability of the EPC9150, a 200 V, high current, pulsed-laser diode driver demonstration board. In a lidar system, used to create 3-D maps for autonomous vehicle applications, speed and accuracy of object detection is critical. As demonstrated by this board, the rapid transition capability of the EPC2034C eGaN FETs provide power pulses to drive the laser diodes, VCSELs or LEDs up to ten times faster than an equivalent MOSFET and in a small fraction of the area, energy, and cost. Thus, enhancing the overall performance, including accuracy, precision, and processing speed as well as the price of a lidar system.

In last month’s Safety & Compliance column in How2Power, “WBG Semiconductors Pose Safety And EMI Challenges In Motor Drive Applications,”[1]Kevin Parmenter made some assertions about the difficulties of using SiC, and to a lesser extent GaN, power semiconductors in large motor-drive applications. This commentary is a response to that article, showing that GaN can be a game changer in low-voltage integrated motors.

The combination of the Renesas dual synchronous GaN buck controller and ultra-efficient eGaN^® FETs from EPC (Efficient Power Conversion) enables high power density and efficiency with the same BOM size and cost as silicon.

EL SEGUNDO, Calif.—  February, 2021 — EPC announces the availability of the EPC9157, a 300 W DC-DC demo board in the tiny 1/16^th brick size, measuring just 33 mm x 22.9 mm x 9mm (1.3 x 0.9 x 0.35 in). The EPC9157 demo board integrates the Renesas ISL81806 80 V dual synchronous buck controller with the latest-generation EPC2218 eGaN FETs from EPC to achieve greater than 95% efficiency for 48 V input to 12 V regulated output conversion at 25 A.  

An automotive application using GaN power devices in high volume is lidar(light detection and ranging) for autonomous vehicles. Lidar technology provides information about a vehicle’s surroundings, thus requiring high accuracy and reliability to ensure safety and performance. This article will discus a novel testing mechanism developed by EPC to test eGaN devices beyond the qualification requirements of the Automotive Electronics Council (AEC) for the specific use case of lidar.

EL SEGUNDO, Calif. — December 2020 — BrightLoop Converters has greatly reduced the size, cost and improved reliability of its latest BB SP DC-DC buck converters thanks to Efficient Power Conversion Corporation’s (EPC) EPC2029 enhancement-mode gallium nitride (eGaN^®) FET transistors. By switching from silicon (Si) transistors to gallium nitride (GaN), BrightLoop was able to increase the switching frequency of their design from 200 kHz to 600 kHz, while keeping the same efficiency. This design change increased the power density of the solution by a factor of approximately two and this resulted in lower cost by enabling the implementation of a smaller enclosure.

EPC’s EPC2029 is an 80 V, 48 A eGaN^® FET featuring a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint.

氮化镓（GaN）技术已实现重大改进，而且它极具成本效益，可以替代MOSFET器件。 从2017年开始，采用氮化镓器件的48 V DC/D转换器开始成为市场上重要的应用。 各种拓扑诸如多相和多级降压转换器，实现具备更高效率的全新解决方案，可以满足IT和车载市场的能源需求。
