AB  - An active scanning proton therapy facility is being de-veloped at Huazhong University of Science and Technol-ogy(HUST). By controlling the deflection position of the beam with scanning magnets at different times, the superposition of discrete spot beams will form a specified shape and dose distribution conformal to the target tu-mour. A high precision and fast response power supply is required to deflect the beam quickly and accurately. In this paper, the TOSCA module in Opera3D is used to model and simulate the scanning magnets and to obtain the equivalent inductance of the magnet. Then the calcu-lated equivalent resistance inductance instead of the magnet is used to design the scanning magnet power supply. A high-voltage bridge is utilized to achieve fast response speed, and a low voltage bridge and PI control algorithm is adopted to ensure power supply accuracy. The Simulation result shows that the designed power supply meets the requirements of response speed and accuracy.
