GaN began to be widely used in data centers

Transphorm, a supplier of high-reliability, high-performance GaN power conversion products, and the Bel Group jointly announced the use of six Transphorm high-voltage GaN FETs in Bel’s titanium-efficiency power supplies, which shows that GaN is used in data center servers , Routers and network switches have deployed high performance, and wide band gap power supply units (PSUs) have maintained a growth trend.

The six GaN-based TET series PSUs are AC to DC power supplies. Including the TET3000 series, which is the industry’s first AC-DC power supply that can achieve titanium efficiency. GaN is used in the AC-DC bridgeless totem pole power factor correction (PFC) power stage. For the output of interest, the same circuit is a variant of the TET3200 series after firmware improvement. The remaining four TET series have a power range of 1.5 to 2.5 kW, in a standard 1U or universal redundant power supply (CRPS) rack installation. The efficiency of the entire series under high voltage is as high as 96%, and the main output is 12 VDC, which makes the PSU obtain the 80 Plus Titanium grade.

GaN: revolutionize data center power supply

Compared with silicon (Si), GaN power converters have fundamental advantages in power applications.Specifically, Transphorm’s GaN FET has been proven to increase the efficiency of AC to DC PFC level to more than 99%, thereby reducing overall system cost while increasing power density (providing more power in the same form factor) ), all of which have high field reliability (GaN-powered TET series

Transphorm’s GaN has multiple TET series, including Bel’s titanium-efficiency front-end AC-DC power supply series, including:

Philip Zuk, vice president of global technical marketing and North American sales at Transphorm, said: “In the past few years, high-voltage GaN has had a positive impact on the industry. The data center market is next. Transphorm’s technical performance exceeds 10 kW in a variety of applications. We The cost of equipment is gradually decreasing, getting closer and closer to traditional silicon. Moreover, we have set industry benchmarks for quality and reliability. We are unparalleled in this field, making our GaN devices the best choice for data center solutions.”
