GaN Systems showcasing GaN advances at China Power Supply Society Conference

GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) says that, at the 23rd China Power Supply Society Conference (CPSSC 2019) in Shenzhen, China (1-4 November), it is giving presentations on the application of GaN in industrial and automotive industries and displaying its latest solutions, design tools, and innovative products.

Additionally, customer demos are being shown that are more efficient, smaller in size and weight, and less expensive than silicon-based power systems.

Also, as part of its commitment to support the design engineering community, GaN Systems is sponsoring the ‘GaN Systems Cup’ design competition, with finalists and winners to be announced on 1 November.


On 3 November, GaN Systems is sharing key insights on new power semiconductor devices and applications:

08.30-09.00 – ‘High efficiency solutions up to 1kW for wireless power transfer applications’;
10.00-10.30 – ‘The effect of dynamic on-state resistance to system losses in GaN-based hard-switching applications’;
15.00-15.30 – ‘GaN device performance in industrial applications’.

Customer demonstrations

GaN Systems is also displaying solutions, design tools and product breakthroughs from game-changing companies.

Products and Tools:

  • GS-065-150-1-D1 high-current, high-power device;
  • GS-065-004,8,11-1-L small-form-factor PQFN devices;
  • 1.2kW high-efficiency bridgeless totem-pole PFC (power factor correction) reference design;
  • IMS reference designs for high power with high power density;
  • 50W and 100W Wireless Power Transfer power amplifiers;
  • EZDrive reference design kit.

Application examples include:

  • mobile device chargers/adapters from 65W to 200W up to 4x smaller with GaN versus silicon;
  • wireless charging examples for consumer, drone, robot and scooter from 30W to 700W;
  • data-center power supply unit (PSU), 50% increase in power density with GaN versus silicon;
  • 5G fixed-wireless access through-wall and through-window CPE wireless power;
  • automotive electric vehicle (EV) traction inverter power designs.

Customer demonstrations highlight end products in the consumer, data-center, industrial and automotive industries, such as AC/DC and DC/DC power supplies, EV traction inverters and high-power wireless charging systems for drones, robots, scooters and 5G applications.

GaN Systems Cup

The winning teams of the GaN Systems Cup design competition are being announced at the live finals and awards ceremony on 1 November. This year’s challenge is to design a high-efficiency, high-power-density AC/DC power supply for data-center server power applications using GaN Systems’ 650V power transistors from design to build. Sponsored by GaN Systems in participation with China Power Supply Society (CPSS), China Power Society Science Popularization Committee and Tsinghua University, the annual challenge supports worldwide innovation in the power electronics industry leveraging the benefits of GaN transistors.
