EPC flies high with eGaN FETs for Solace Power’s wireless power

GaN-based power devices from Efficient Power Conversion (EPC) are by Solace Power in 250W wireless power platforms for 5G, aerospace, automotive, medical, and industrial applications.

The two companies have collaborated to incorporate EPC’s 200V enhancement-mode gallium nitride (eGaN) power transistors in the modular platform which shares the same Equus architecture. The modular systems enable up to 250W of transmitted power with six degrees of spatial freedom.

“We’re excited to collaborate with EPC to further push the limits of our capacitive wireless power platform and to deliver previously unachievable solutions with a higher power requirement,” said Solace Power CEO, Michael Gotlieb. “Solace focuses on delivering complete, modular systems which are pre-tested for CISPR/FCC compliance and optimised in-house for rapid development in real world applications. These new solutions solve the most important challenges for applications requiring 200W or more,” he explained.

For wireless power applications with higher power demands than traditional consumer devices, existing silicon-based transistors become inefficient. To address this limitation, Solace selected a 200V GaN-based power transistor from EPC for a 250W wireless power application platform, which cannot be met by existing silicon-based transistors, reports EPC.

“Wireless power is ready to be incorporated into our daily lives and the modular platform that Solace Power has developed, using highly efficient, low cost GaN transistors, will improve design cycle times and help new industries implement wireless power quickly and inexpensively,” commented Alex Lidow, CEO and co-founder of EPC.

EPC was the first company to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs to replace power MOSFETs in applications such as DC/DC converters, wireless power transfer, envelope tracking, RF transmission, power inverters, remote sensing technology (Lidar) and Class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs.

EPC also has a growing portfolio of eGaN-based integrated circuits that provide

Solace Power develops intelligent wireless power-based solutions featuring proximity sensing and data. Its patented Resonant Capacitive Coupled (RC²) technology provides industrial grade, decoupled power for automotive, defence, medical, industrial automation and telecomms.
