實現按電流平均值自動均流法的一個實用電路

摘要：給出了一個實現按電流平均值自動均流的實用電路。在該電路中，均流母線發生短路故障時能自動報警；并聯電源模塊中任意一個模塊出現失效故障時，能自動切斷其對母線的影響并告警。 敘詞：開關電源 均流 實用電路 Abstract：In view of the automatic current-sharing method according to current mean value,a practical automatic current-sharing circuit is designed for switching power supply.The circuit can sound an alarm automatically when a short-circuit fault occurs in the current-sharing bus;in addition,it can cut off its effect on the bus automatically and can give an alarm,when any one in the parallel module of power supply no longer has any effect.
