氮化鎵(GaN)正在改變工程師設計功率轉換系統的方式。在許多應用中,與傳統矽 MOSFET 相比,GaN 能實現更高的開關頻率、更高的效率和更高的功率密度。但 GaN 究竟在哪些方面真正優於矽?又在甚麼情況下採用 GaN 才具有工程和經濟上的合理性?在 EPC GaN 問答直播(Q&A LIVE)的首期節目中,EPC 首席執行官 Alex Lidow 回答了工程師關於 GaN 與矽技術對比的問題,涵蓋電壓範圍、開關損耗、功率密度、瞬態響應、PCB 佈局、寄生電感、閘極驅動、可靠性、成本以及與碳化矽的比較。此次討論為評估 GaN 在下一代功率轉換系統中應用的工程師提供了實用指導。

Gallium nitride (GaN) power transistors designed for efficient power conversion have been in production for seven years. New markets, such as light detection and ranging, envelope tracking, and wireless charging, have emerged due to the superior switching speed of GaN. These markets have enabled GaN products to achieve significant volumes, low production costs, and an enviable reliability reputation. All of this provides adequate incentive for the more conservative design engineers in applications such as dc–dc converters, ac–dc converters, and automotive to start their evaluation process. So what are the remaining barriers to the conversion of the US$12 billion silicon power metal–oxide–semiconductor field-effect transistor (MOSFET) market? In a word: confidence. Design engineers, manufacturing engineers, purchasing managers, and senior management all need to be confident that GaN will provide benefits that more than offset the risk of adopting a new technology. Let’s look at three key risk factors: supply chain risk, cost risk, and reliability risk.
