Electronica 2018: By using high voltage GaN FETs from Transphorm, Delta Electronics has been able to reduce the size of its 80Plus Platinum 800W power supply by 25%.
GaN technology reduces system size for mission-critical applications.
The space saving allows for a back-up lithium-ion battery which can keep connected servers running for 60 seconds.
The decision to use HV GaN devices in the CRPS form factor depended partly on meeting new product reliability and power density objectives, reports the company. It also repurposed its existing design, a standard PFC continuous-conduction mode (CCM) boost converter.
The use of GaN in the server power market is increasing and is set to be worth approximately $50million by 2022, making server power supplies the third largest sector for the GaN power device market
Gallium Nitride use within the server power supply market is ramping. Research firm Yole Développement projects the market’s growth to reach approximately $50 million by 2022 to make server power supplies the third largest segment within the total GaN power device market.
