      • IGBT的開關損耗不僅僅依賴于驅動電阻,也依賴于驅動環路的電感,而實際用戶系統的驅動環路電感常常不同于數據手冊的測試平臺的驅動環路電感。
      • 驅動中加入柵極和發射極電容是很常見的改善EMC特性的設計方法,而使用該柵極電容會影響IGBT的開關過程中電流變化率dIc / dt和電壓變化率dVce / dt,從而影響IGBT的開關損耗
      • 實際系統的驅動電壓也常常不同于數據手冊中的測試驅動電壓,在IGBT模塊的數據手冊中,開關損耗通常在±15V的柵極電壓下測量,而用戶的驅動電壓有時也并非這個電壓數值。
      • 數據手冊通常會在較小的母排雜散電感下進行開關損耗測試,而實際系統的母排或者PCB的布局常常會存在比較大的雜散電感。
