Transphorm announced that Yaskawa Electric Corporation is launching the mass production of world’s smallest power conditioner in its class – and the first to use a GaN power module. Based on Transphorm’s EZ-GaN IP-protected platform, Yaskawa’s Enewell-SOL V1 series 4.5kW indoor PV inverter will be distributed in Japan, with a targeted annual production of 34,000 systems.
The new 98%+ peak efficiency, GaN-based power conditioner operates at three times higher frequencies than silicon-based modules. The unit is half the size of competitive solutions thanks to its smaller magnetics and heat sinks. And its exceptional efficiency allows for fan-free, low noise operation. Powered by Transphorm, the Yaskawa PV inverter’s TPD3215M module utilizes the only qualified, high-voltage (600V) GaN-based solution on the market today. Yaskawa fully exploited the system value proposition of Transphorm GaN by making its record-breaking performance possibilities a commercial reality. This level of mass production for the rapidly growing residential PV inverter segment is one more step toward establishing GaN as the new power conversion platform.
Over the last several years, GaN semiconductors have emerged as a leading technology enabler for the next wave of compact, energy-efficient power conversion systems – ranging from ultra-small adapters, high power density PCs, server and telecom power supplies, to highly efficient PV inverters and motion control systems. The adoption of EZ-GaN technology by a leading international company, such as Yaskawa, validates both the quality and performance of Transphorm’s GaN products in power converter/inverter systems.
