In the PAL-XFEL, 632 magnet power supplies (MPS) have been operated since 2016. High current unipolar MPSs(>100A) were configured buck mode with single power stack or two. The corrector MPSs for low current were the H-bridge type for bipolar current driving. The nine different types of MPS were installed for beam dy-namics in the PAL-XFEL machine. All MPSs had been tested and confirmed their performances before installa-tion. We described here the status of the MPS operation after installation on 2016.

A high stable magnet power supply (MPS) was devel-oped, which was a bipolar type with 200A of the output current at the 40V of output voltage. The MPS has been implemented by the digital signal processing technology using the DSP, FPGA, ADCs and so on. The output cur-rent stability of the MPS showed about 4 ppm peak-to-peak in a short term experiment at the 200A of its full output current. This paper shows the several design con-siderations being implemented to this high stable MPS. Some experimental data such as output stability, some waveforms and so on are given in this paper.
