易事特(300376.SZ):取得1項發明專利證書 為電網過零補償方法
格隆匯 05-10 17:50

格隆匯5月10日丨易事特(300376.SZ)公佈,公司近日取得中華人民共和國國家知識產權局頒發的發明專利證書1項,專利名稱為電網過零補償方法。

發明專利《電網過零補償方法》提出一種用於高頻整流器的電網電壓過零補償技術及實現方法。通過對控制高頻功率變換單元的三相調製電壓進行自適應補償,解決因BOOST電感上的壓降在電網過零點處形成的電流畸變所導致的諧波增生問題,有效降低電網側輸入電流總諧波畸變率(THDI)。該技術在公司相關UPS電源、直流充電模塊等產品中得到有效應用。

上述發明專利技術屬於與公司UPS電源、直流充電樁、儲能變流器等產品密切相關的核心技術,專利的取得不會對公司近期生產經營產生重大影響,但有利於公司知識產權系統建設,鞏固公司技術創新發展的領先地位。
