Transphorm’s 600V GaN power conversion adopted by Delta

Transphorm Inc of Goleta, near Santa Barbara, CA, USA (which designs and delivers power conversion devices and modules) has been invited to present at the exclusive Power Design Engineering event in Shanghai (22 November) of Taiwan-based manufacturer Delta Electronics Inc.

Transphorm will present its JEDEC-qualified gallium nitride on silicon (GaN-on-Si) high-electron-mobility transistor (HEMT) products and applications based on its proprietary EZ-GaN technology. Participation as the only invited external supplier at the internal event, where Delta will share technology insights across a variety of areas at its Hangzhou Design Center (HDC) and Shanghai Design Center (SDC), will allow Delta’s engineering force to proliferate the adoption of 600V GaN products in applications ranging from power supplies to various other inverters/converters, expects Transphorm.

With its TPH3006PS GaN HEMT, Transphorm has established what is claimed to be the industry's first qualified 600V GaN device platform. The GaN transistor combines low switching and conduction losses, offering reduced energy loss of 50% compared to conventional silicon-based power conversion designs, it is reckoned. The TO-220-packaged device features RDS(on) of 150 milliohms, Qrr of 56nC, and high-frequency switching capability that enables compact lower-cost systems.

“We have long recognized gallium nitride as providing unprecedented power conversion efficiency as well as reduced-form-factor in systems,” says Dr Alpha Zhang, director of Delta SDC/HDC and vice chairman of the China Power Supply Society. “With the proof that high-voltage GaN-on-Si is qualified and available for production, we look forward to realizing the benefits of GaN being implemented into real power products in the marketplace.”

Transphorm says that its efficient, compact and easy-to-embed modules simplify the design and manufacturing of a wide variety of electrical systems and devices, including power supplies and adapters, motor drives, and inverters for solar panels and electric vehicles. It claims that its proprietary EZ- GaN platform can reduce power system size, increase energy density and deliver high efficiencies across the grid.
