藍海華騰(300484.SZ)取得發明專利證書 涉一種檢測IGBT使用壽命是否達標的方法及裝置
格隆匯 04-17 15:48

格隆匯4月17日丨藍海華騰(300484.SZ)公佈,公司於近日收到中華人民共和國國家知識產權局頒發的發明專利證書,涉一種檢測IGBT使用壽命是否達標的方法及裝置。

該發明專利提供的一種檢測IGBT使用壽命是否達標的方法,通過根據用户設置的參數測試對象生成相應的測試信號;根據測試信號對IGBT連續進行N次循環測試;當IGBT的工作温度首次大於温度閾值時,獲取IGBT芯片與外殼的第一温差值;若IGBT的第一温差值大於0,在第N次測試中,當IGBT的工作温度大於所述温度閾值時,獲取IGBT芯片與所述外殼的第二温差值;若IGBT的第二温差值與IGBT的第一温差值的差大於預設閾值,輸出第一信號以提示IGBT使用壽命不達標;反之,輸出第二信號以提示IGBT使用壽命達標。使得檢測IGBT使用壽命是否達標的步驟更簡單,降低了檢測成本,更易推廣。

上述發明專利的取得,對公司的生產經營情況不構成重大影響,但有利於進一步確立公司的自主知識產權優勢,並對公司的技術創新、產品創新、市場及品牌影響力提升等方面產生積極的影響,從而提升公司的核心競爭力。
