Delta Electronics vermindert stroomverbruik met Transphorm’s High-Voltage GaN FETs
GOLETA, Calif.–(BUSINESS WIRE)–
Een standaard PFC CCM Boost Converter met behulp van GaN ontketent nieuwe mogelijkheden voor energiebeheer
Transphorm Inc. en Delta Electronics hebben vandaag onthuld dat de nieuwste innovatie van de fabrikant van de voedingseenheid (PSU) voortkomt uit het praktische gebruik van Transphorm’s hoogspanning (HV) GaN FETs. Delta’s nieuwste 80plus Platinum 800 Watt PSU biedt nu een back-up lithium-ionbatterij. Mocht een datacenter stroom verliezen, dan zal de batterij van de PSU de aangesloten servers één minuut lang genoeg laten draaien om een goede stroomonderbreking mogelijk te maken. Door het gebruik van GaN is Delta in staat om de grootte van het stroomsysteem met ~25 procent te verminderen, waardoor de batterij kan worden opgenomen in de standaard CRPS-vormfactor.
Delta Electronics Shrinks Power Supply with Transphorm’s High-Voltage GaN FE

A Standard PFC CCM Boost Converter Using GaN Unleashes New Power Management Capabilities
Transphorm Inc. and Delta Electronics disclosed today that the power supply unit (PSU) manufacturer’s newest innovation comes from practical use of Transphorm’s high-voltage (HV) GaN FETs. Delta’s latest 80Plus Platinum 800 Watt PSU now offers a backup lithium-ion battery. Should a data center lose power, the PSU’s battery will keep connected servers running for one minute—long enough to allow for a proper power down sequence. The use of GaN enabled Delta to reduce the power system size by ~25 percent, allowing for battery inclusion within a CRPS form factor.
The advanced design comes from Delta’s deepening experience working with GaN power semiconductors in an effort to equip customers with high performing power solutions. The decision to use HV GaN devices depended partly on meeting new product reliability and power density objectives. Additionally, Delta sought to successfully repurpose its existing PSU design—a standard PFC continuous-conduction mode (CCM) boost converter.
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. This would position server power supplies as the third largest segment within the total GaN power device market (~$450 million by 2022) behind broad industrial power supplies1.
