	The measurement accuracy of direct current-current transformer (DCCT) is one of the key factors influencing the output of high-precision direct current power supply.

The measurement accuracy of direct current-current transformer (DCCT) is one of the key factors influencing the output of high-precision direct current power supply. In this paper, a calibration system designed by measuring resistance principle with a high accuracy direct current comparator (DCC) was presented for DCCT whose measurement accuracy is better than 10^-5. The system can achieve high-precision calibration of DCCT within the measurement range of 0-400 A, and the uncertainty of the system calibration is better than 1.1×10-6 in the whole range. The accuracy and linearity of DCCT are tested to verify the accuracy of the whole calibration system, thereby the current accuracy of the magnet power supply can be further improved.

Superconducting Wiggler (SCW) is an important development direction of insertion devices for modern light sources. It is also the key technology of High Energy Photon Source Test Facility (HEPS-TF) insertion device system research. SCW control system involves power supply, cryogenics，vacuum and other devices, control. Serial port server was built for the SCW control system, with EPICS DB to make the PID algorithm for heater and superconductor cavity pressure, temperature, and with Ziegler-Nichols method to quickly find appropriate PID parameters.
