眾所周知，光伏儲能電池管理系統BMS充放電回路中的MOS管，會在開關瞬間電流的突變而產生漏極尖峰電壓，給MOS管帶來威脅甚至損壞。功率管開關速度越快，產生的過電壓也就越高。為了保護MOS管免受其威脅和損壞，電路保護器件廠家東沃電子技術推薦在DS間選用TVS二極管進行浪涌過壓保護。東沃光伏儲能電池管理系統BMS充放電回路MOS管浪涌過壓保護方案圖如下所示：

從方案圖中可知，東沃電子技術在MOS管DS之間增加TVS瞬態抑制二極管，TVS二極管具體選型要根據電池的最高電壓和MOS管的耐壓來選擇。根據PACK電池包電壓，東沃電子技術推薦選用SMCJ系列和5.0SMDJ系列TVS二極管，具體型號如下所示：

以上是東沃光伏儲能電池管理系統BMS充放電回路MOS管浪涌過壓保護方案及TVS二極管選型推薦，如有特殊需求，歡迎前來探討。浪涌靜電防護方案，找東沃電子，電路保護不迷路！東沃電子有專業工程師設計方案并協助選型，有免費的EMC實驗室供您測試。方案中選用到的TVS二極管SMCJ15CA、SMCJ18CA、SMCJ22CA、SMCJ24CA、SMCJ33CA、SMCJ45CA、SMCJ60CA、5.0SMDJ60CA、SMCJ75CA、5.0SMDJ75CA、SMCJ85CA、5.0SMDJ85CA、SMCJ90CA、5.0SMDJ90CA，東沃電子已全面量產、品質穩定、高可靠性、交期迅速、廠家價格、免費樣品、免費EMC測試、免費選型，歡迎廣大新老客戶前來咨詢：137 5773 6996（微信同號）余工
