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.
pollution, and the unreliability of energy grids. 

Natural disasters (e.g. loss of power from hurricanes, earthquakes, snow storms) and ‘wildfire prevention’ power outages (called PSPS for public safety power shutdown) imposed by utility companies in California has resulted in an increasingly unreliable energy grid:

  • Highly efficient residential and commercial energy storage systems (ESS) using GaN technology will enable distribution, local storage, and on-demand access to renewable energy. Both cost reduction and increasing energy security demands will drive this.
  • With the price of ESS dropping and increased residential and commercial interest, sales of ESS will continue to rise, particularly in states such as California and Texas. 
  • Smaller ‘all-in-one’ products such as solar panels with solar inverter and battery storage built in will provides AC power 24/7 if the local power grid goes down. GaN’s efficiency in power conversion (lighter weight and smaller ESS) will be a key component to enable this kind of product design.
  • The movement from lead acid to lithium ion batteries will lead to declining battery costs and the development of smaller, lightweight, energy-dense batteries that will pair with GaN technology-based converters and inverters to lead the revolution in ESS.
  • Interest in local micro-grids for both business and residences will grow as individuals look to increase their energy security and leverage a collective of individuals ESSs.


In 2019, GaN transistors drove a range of  smaller, lighter, and higher power adapters/chargers in the aftermarket. In 2020, GaN Systems predicts:

  • Growing momentum for USB-C and USB-PD products which can be used to charge any compatible product.  The days of one charger for one piece of electronics will quickly disappear and the days of one charger for all consumer electronics will begin to dominate. A single adapter/charger that handles every device regardless of varying voltages for a phone (5V), tablet (12V), or laptop (19V).
  • In-box GaN adapters/chargers (shipping inside the box with the computer or with the mobile phone) will start to become
