Top 2020 technology trends in power electronics unveiled by GaN Systems
Gallium nitride chip designer GaN Systems has released its top four power trends for 2020.

GaN Systems has been looking at the power trends for data centers, electric vehicles, renewable energy systems, industrial motors and consumer electronics over the next 12 months.

Electric Vehicles

In 2019, it became increasingly clear that the near future of transportation revolves around electric vehicles, and in the longer term around autonomous vehicles that are also electric. Today, there are 5.1 million electric vehicles on global roads. The stage is set for a massive hit to the global energy grid as 125 million electric vehicles are expected to be on the roads by 2035. 

The evolution of the design of Chargers and Traction Inverters will play a major role in automotive design studios in 2020, and then onto the public roads in the years following. In order to address the long-standing issue of ‘range anxiety,’ the number of public electric charging stations will continue to grow, with an increasing focus on solar power and plug standardization.

In 2020, GaN Systems predicts: 

  • Designs from major automotive manufacturers will focus on increased efficiency, power density and reduced weight with a focus on Chargers and Traction Inverters.
  • Battery technology will continue to improve and then, combined with lighter weight vehicles, will contribute to increase vehicle range and consumer acceptance.
  • Autonomous Vehicles will see technology evolution in Level 2 to Level 3 autonomy and improved safety systems using LiDAR with GaN technology  used in the design of higher power, longer range detection systems 

5G Rollout

In 2019, the 5G rollout was slower than expected, primarily due to the issues around communications service providers (CSPs) upgrading 4G infrastructure within 5G areas of coverage. Nevertheless, according to Gartner research, 5G services have already begun the U.S., South Korea, and some European countries, including Switzerland, Finland and the U.K.                        

In China, 5G commercial services are now available in 50 cities, including Beijing, Shanghai, Guangzhou and Shenzhen, according to Chinese state news agency Xinhua. In Shanghai, nearly 12,000 5G base stations have been activated to
