GaN Reliability Testing Beyond AEC Proves Robustness for Automotive Lidar Applications

Gallium nitride (GaN) power devices have been in volume production since March 2010 and have established a remarkable field-reliability record. 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 discuss a novel testing mechanism developed by Efficient Power Conversion (EPC) to test eGaN devices beyond the qualification requirements of the Automotive Electronics Council (AEC) for the specific use case of lidar.

氮化鎵元件緩解了矽元件的問題

就像生活要面對現實一樣,老年人離開舞臺而讓位給年輕人,矽元件也是需要向現實低頭。 隨著氮化鎵元件的問世和普及,正逐步淘汰舊有可靠的矽元件。 在過去的四十年中,隨著功率MOSFET元件的結構、技術和電路拓撲的創新與不斷增長的電力需求同步發展,電源管理的效率和成本一直以來得以穩步改善。 但是,在業界發展的新時代,隨著矽功率MOSFET元件接近其理論極限,其演進速度下降了很多。 同時,新材料氮化鎵的理論性能極限穩步發展,其性能極限比老化的MOSFET元件高出6,000倍,並且比目前市場上最好的氮化鎵產品高出300倍。

Designing An Ultra-Thin Stepdown Converter: Multiphase Vs. Multilevel

Over the past decade computers, displays, smart phones and other consumer electronics systems have become thinner while also becoming more powerful. As a result, the market continues to increase its demand for thinner power supply solutions with greater power density. This article examines the feasibility of adopting various non-isolated dc-dc stepdown topologies for an ultra-thin 48-V to 20-V, 250-W power solution.

Integrated GaN Power Stage for eMobility

Brushless DC (BLDC) motors are a popular choice and are finding increasing application in robotics, drones, electric bicycles, and electric scooters. All these applications are particularly sensitive to size, weight, cost, and efficiency. A monolithically integrated GaN power stage is demonstrated powering a 400 W capable BLDC motor with low switching losses and significant savings in size and weight.

GaN Integrated Power Stage – Redefining Power Conversion

Beyond just performance and cost improvement, the most significant opportunity for GaN technology to impact the power conversion market comes from its intrinsic ability to integrate multiple devices on the same substrate. GaN technology, as opposed to standard silicon IC technology, allows designers to implement monolithic power systems on a single chip in a more straightforward and cost-effective way.

Gallium Nitride Integration: Breaking Down Technical Barriers Quickly

An integrated circuit made using GaN-on-Si substrates has been in production for over five years. The ultimate goal is to achieve a single component IC that merely requires a simple digital input from a microcontroller and produces a power output that drives a load efficiently, reliably under all conditions, in the smallest space possible, and economically. Discrete power transistors, whether silicon-based or GaN-on-Si, are entering their final chapter. Integrated GaN-on-Si can offer higher performance in a smaller footprint with significantly reduced engineering required.
