One DC power supply controller was designed to test interface of DC current-stabilized PS in HIRFL. More than 250 power supplies have been replaced by new ones since 2000. And the interface between PS and control system is also very different compared with the old ones. It is necessary to design a controller to test the interface. In fact, the controller simulates the control system to control the PS. So it should give the analog reference to PS by D/A, and read the PS's output current and voltage signal by A/D. At the same time, the controller can control the operation of PS, such as turn on and turn off, and also read back all status of PS.
