Efficient Power Conversion (EPC) has signed a comprehensive licensing agreement with Renesas Electronics, granting Renesas access to EPC’s mature low-voltage eGaN technology. The two companies will collaborate to establish internal wafer manufacturing capabilities, and Renesas will serve as a second source for selected mass-produced EPC GaN devices, strengthening supply chain resilience.
As demand for higher efficiency, greater power density, and lower carbon emissions increases, gallium nitride (GaN) is rapidly replacing silicon in power electronics. Compared to silicon devices, GaN transistors offer:
- Higher efficiency
- Faster switching speeds
- Significantly smaller package sizes
Renesas' GaN technology is widely used in:
- AC-DC power supplies
- EV charging systems
- Solar inverters
- Industrial motor drives
These solutions maintain high reliability even under demanding operating conditions.
Following its acquisition of Transphorm to enhance high-voltage GaN capabilities, Renesas will now expand into low-voltage GaN through this partnership. The combined portfolio will cover applications from AI power architectures (48V–12V/1V) to EV charging, solar inverters, and industrial motor drives.
This collaboration marks another significant step in accelerating GaN adoption across global markets.
