In this video from Power Electronics News, a lineup of distinguished speakers from semiconductor companies shares insights into groundbreaking developments in gallium nitride– and silicon carbide–based power devices.
The GaN speakers address two critical questions shaping the future of wide bandgap:
- The significance of substrate material choice for GaN-based power devices. They elaborate on how this choice impacts device performance, reliability and manufacturability and discuss how researchers are tackling substrate-related challenges.
- Specific market segments where GaN devices are outperforming traditional silicon-based solutions, driving adoption and revealing the technology direction of their respective companies. The speakers include:
- Robert Taylor, applications engineer/general manager industrial applications at Texas Instruments
- Michael de Rooij, VP of applications engineering at EPC
- Balu Balakrishnan, CEO of Power Integrations

宜普电源转换公司首席执行官兼共同创办人Alex Lidow接受DIGITIMES专访,提到GaN主要会被应用在650V及以下市场。反之碳化硅则是主导650V以上的市场,它可望取代硅基绝缘栅极双极性晶体管。宜普也在开发对速度及尺寸特性极为要求的400V以下市场。且致力于制造比Si功率元件拥有更高性能、更具成本竞争力的GaN元件。

Efficient Power Conversion (EPC) strengthens market leadership in gallium nitride power conversion by adding significant 8-inch manufacturing capacities in collaboration with Vanguard International Semiconductor Corporation (VIS).
EL SEGUNDO, Calif.— December 6, 2022 — EPC, the world’s leader in gallium nitride (GaN) power FETs and integrated circuits (ICs), and Vanguard International Semiconductor Corporation (VIS), a leading specialty IC foundry service provider, today jointly announced a multi-year production agreement to produce gallium nitride-based power semiconductors. EPC will utilize VIS’ 8-inch (200 mm) wafer fabrication capabilities, significantly increasing manufacturing capacities for EPC’s high-performance GaN transistors and integrated circuits. Manufacturing will commence in early 2023.
