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.

Efficient Power Conversion (EPC) publishes Phase-12 Reliability Report adding to the extensive knowledge found in their first eleven reports. With this report, EPC demonstrates field experience of 226 billion eGaN ^® device hours and a robustness capability unmatched by silicon power devices.

EL SEGUNDO, Calif.— January 2021 — EPC announces its Phase-12 Reliability Report, documenting the strategy used to achieve a remarkable field reliability record. eGaN devices have been in volume production for more than eleven years and have demonstrated very high reliability in over 226 billion hours of operation, most of which are in vehicles, LTE base stations, and satellites, to name just a few applications with rigorous operating conditions.

Gallium nitride (GaN) transistors have been in mass production for over 10 years. In their first few years of availability, the fast switching speed of the new devices – up to 10 times faster than the venerable Si MOSFET – was the main reason for designers to use GaN FETs. As the pricing of GaN devices normalized with the MOSFET, coupled with the expansion of a broad range of devices with different voltage ratings and power handling capabilities, much wider acceptance was realized in mainstream applications such as DC-DC converters for computers, motor drives for robots, and e-mobility bikes and scooters. The experience gained from the early adopters has led the way for later entrants into the GaN world get into production faster. This article is the first in a series of articles discussing three topics that can help power systems designers achieve the most out of their GaN-based designs at the lowest cost. The three topics are: (1) layout considerations; (2) thermal design for maximum power handling; and, (3) EMI reduction techniques for lowest cost.

就像生活要面对现实一样，老年人离开舞台而让位给年轻人，硅器件也是需要向现实低头。 随着氮化镓器件的问世和普及，正逐步淘汰旧有可靠的硅器件。 在过去的四十年中，随着功率MOSFET器件的结构、技术和电路拓扑的创新与不断增长的电力需求同步发展，电源管理的效率和成本一直以来得以稳步改善。 但是，在业界发展的新时代，随着硅功率MOSFET器件接近其理论极限，其演进速度下降了很多。 同时，新材料氮化镓的理论性能极限稳步发展，其性能极限比老化的MOSFET器件高出6,000倍，并且比目前市场上最好的氮化镓产品高出300倍。

It’s getting harder to avoid using GaN power transistors and ICs, says Alex Lidow. There are many reasons to use GaN-on-Si power transistors such as eGaN FETs, in telecoms, vehicles, healthcare and computing. Smaller, faster, lower cost, and more integrated, GaN-on-Si devices have spent a decade gaining the confidence and trust of designers across the spectrum of power conversion applications.

When the issue invariably turns to the packaging of the power semiconductor – transistor, diode, or integrated circuit – the requests for improvement fall into six categories:

1. Can you make the package smaller?
2. Can you reduce the package inductance?
3. Can you make the product with lower conduction losses?
4. Can you make the package more thermally efficient?
5. Can you sell the product at a lower price?
6. Can you make the package more reliable?
