全球領導電動車動力系統解決方案供應商緯湃科技 (Vitesco Technologies) 今天宣布與氮化鎵功率半導體全球領導廠商 GaN Systems 建立策略合作關係。GaN 功率半導體在車用領域具有極大的市場潛力,與矽功率元件相比,GaN 功率電晶體能使電動車動力系統更高效率、更小且具經濟效益。 電動車中充電及電力轉換應用將成為 GaN 功率半導體的最佳突破點。雖然目前 GaN 功率元件在車用領域的發展才初起步,但 GaN Systems 與 Vitesco 這次的策略結盟將擴大 GaN 在電動車應用的版圖,幫助電動車開發商進一步提高行駛里程及用電效率。 「氮化鎵功率電晶體是電力電子技術的未來,」GaN Systems 全球執行長 Jim Witham 表示,「氮化鎵將進一步縮小功率元件的尺寸,同時提高效率並減少開發成本。我們很榮幸能夠與 Vitesco 合作,擴大我們在車用領域的布局。」 GaN 功率半導體的優勢 電動車中動力系統的用電效率深受功率元件及能源轉換效率影響,在每次能源轉換間都有部分的能源損耗透過熱的形式產生,進而影響電動車整體傳動系統的效率,現有矽元件在效率上的不足便帶動了寬能隙半導體的發展,其中發展較成熟的便屬氮化鎵 (GaN) 及碳化矽 (SiC),它們能夠實現更快速的切換頻率、減少能源損耗,大幅縮減動力系統尺寸及物料成本。Vitesco 已經成功整合 SiC 元件於其高效率的電動車牽引逆變器平台中,而 GaN 便是它們的下一個發展重點。 「氮化鎵功率電晶體能有效將熱損耗降至最低,尤其是在及高切換頻率下的開關損耗,且氮化鎵在各物理特性層面皆大幅優於矽,掌握先機發展這項將左右未來的技術對我們來說相當重要,」Vitesco Technologies 電汽化事業部總經理 Gerd Rösel 表示。 雙方合作對 GaN 功率半導體加速進入車用領域的十分重要。GaN 功率電晶體的卓越效率能夠減少矽統對散熱的需求,實現更為精簡的機構設計,進而優化電動車的效率及里程。Rösel 進一步指出,「與 GaN Systems 的合作將為…
