晶闸管有源逆变器的停电保护方法

Power-cut Protection for the Thyristor Inverter with Supply

讨论了蓄电池化成和充放电用的晶闸管电源中有源逆变失败的保护 .加入晶闸管辅助关断电路可以完善蓄电池充放电电源性能 .

The protection for the failure of the inverter with supply in the thyristor inverter source to be used for battary formation and as charge/discharge is studied.The auxiliary circuit to switch off the thyristor in the inverter is added in order to improve the properties of battary charge/discharge source.The signal sensing for power off and the implement of the control sourcetd be used for the protection is analysised in this paper.
