多路可控可监测稳压电源的设计

Design of Monitorable and Controllable of Multiple Power Supply

该文设计了一种电压、电流值可实时监测的多路可控线性稳压电源,可将霍尔传感器所监测的电压电流值通过USB接口实时显示到上位机软件界面,且可根据所监测的电流值的大小与预先设定的值进行比较,如果超出设定值可控制该路断开,实现过流保护。根据要求该电源可由上位机软件控制将某一路输出进行10%拉偏,该电源输出稳定、性能可靠、已成功用于某存储系统测试设备。

This paper designs a voltage and current values can be controlled real-time monitoring of multiple linear regu-lated power supply,the voltage and current values collected by Hall sensors can be real-timed display to the PC soft-ware interface through the USB interface,and the collected current value can be compared with that of pre-set value,if it exceed the pre-set value,it can be controlled off this circuit,achieve over-current protection.On request,the power supply can be controlled to a host computer software output to 10% of the pull side,this power output stablity,reliable performance,has been successfully apply on a test equipment for a storage systems.
