This paper presents the air core magnet power supply for the Pohang Light Source. The required current to energize the air core magnet was ±5 A with the high precision of ~2ppm resolution to accomplish a stable beam orbit correction. This power supply has been implemented using the digital signal processing technology and shows the high stability and other good responses. Various experimental results such as stability, bandwidth and simulation are given in this paper.
