NSTU Develops Devices for Compact Power Supplies for Data Centers and Drones
The technology could support the independent development of Russia’s telecommunications sector.
Researchers at Novosibirsk State Technical University (NSTU) have reported successfully producing prototype converters based on gallium nitride transistors. These are expected to form the basis for new compact power supplies for drones and data centers.
“Gallium nitride has a bandgap that is three times wider than silicon, allowing semiconductor devices to operate at higher voltages. GaN-based transistors can switch at frequencies of several megahertz and higher, reducing the size of passive components in converters,” said Maxim Dybko, an associate professor at NSTU.
According to the researcher, improving secondary power supplies is critical for the independent development of the telecommunications sector. Further research and testing are currently underway. The technology will enable bare dies to be mounted directly onto printed circuit boards alongside packaged components, making devices more compact and lighter while maintaining full functionality.
