摘要
Abstract
This paper focuses on the high reliability design of power supply for carrier communication circuit from two aspects of over-current and shortcut protection and ripple suppression.Compared with the DC/DC and LDO protection circuit,the circuit designed by this paper not only has the over-current and shortcut protection function,but also with under voltage protection,which greatly improves the reliability of the circuit and reduces the power consumption under the protection state to achieve low power consumption.The LC filter is used to reduce ripple voltage and improve ca-pacity of resisting disturbance through using the butter worth low-pass filter normalized design.Test results show that the circuit designed by this paper works well,and has been tested by state grid metering center.关键词
