Power semiconductors are used across many areas of e-mobility, with different technologies suitable for each part of a vehicle, depending on the voltage and current requirements, while emerging tech is allowing smaller systems to be implemented. With GaN and SiC technologies maturing and coming down in price, adoption is growing, and the technologies are increasingly dominating the design and development of e-mobility powertrain and power systems.

Gallium Nitride (GaN) FETs have revolutionized the power electronics industry, offering advantages such as smaller size, faster switching, higher efficiency, and lower costs compared to traditional silicon MOSFETs. However, the rapid evolution of GaN technology has sometimes outpaced the development of dedicated GaN-specific gate drivers and controllers. Consequently, circuit designers often turn to generic gate drivers designed for silicon MOSFETs, necessitating careful consideration of various factors to ensure optimal performance.

宜普電源轉換公司聯合創辦人暨執行長Alex Lidow表示，GaN的成本競爭力亦與Si MOSFET並駕齊驅，潛在爆發力更有過之而無不及，目前最關鍵就是得重塑諸多研究者的老舊觀念，認為GaN昂貴到碰不得。GaN的技術正迎來轉捩點，在先進運算、車用電子、太空電子及消費電子等新型應用設計多數採GaN技術，而非Si MOSFET。

Case Spotlights Next-Gen Tech Replacing Silicon

(El Segundo, California)—Efficient Power Conversion Corporation (EPC), the global leader in gallium nitride (GaN) technology, today filed complaints in federal court and in the U.S. International Trade Commission (ITC) asserting four patents of its foundational patent portfolio against Innoscience (Zhuhai) Technology Company, Ltd. and its affiliates (collectively, Innoscience).  These patents cover core aspects of the design and manufacturing process of EPC’s proprietary enhancement-mode gallium nitride power semiconductor devices.  These patents encompass innovations that enabled GaN-based power devices to mature from a research project to a mass-producible high-volume alternative to silicon-based transistors and integrated circuits with GaN devices having higher efficiency, smaller size, and lower cost. 

Since the launch of GaN-on-Si enhancement mode power transistors in March 2010 there has been a slow but monotonic shift towards adoption and replacement of silicon-based power MOSFETs. Initial adoption came from risk-taker visionaries in applications such as lidar, high-end audio amplifiers, robots, vehicle headlamps, and high-performance DC-DC converters. For the expansion of GaN for power conversion to get beyond the early adopters, a more user-friendly format than the WLCP needed to be developed. This format, however, needed to preserve the key attributes of small size, low RDS(on), high speed, excellent thermal conductivity, and low cost. In other words, the best package would be the least amount of package technically possible. Enter the PQFN…

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.

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).

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.
