High Energy Photon Source-Test Facility (HEPS-TF) is a pre-research project for the construction of high energy synchrotron radiation source in the 12th five-year plan period. The purpose is to research the key technology and develop the key equipment of high energy synchrotron radiation source. Superconducting 3W1 magnet is the first self-develope...
According to the nonlinear characteristics of inductance and output current of superconducting magnet, a new digital closed-loop control algorithm for the load of superconducting magnet power supply with large time constant is proposed.
This algorithm is quite different from the traditional algorithm and can attain the independent tracking and adjustment of the control target. Finally, by testing the ripple, error and stability of superconducting 3W1 magnet power supply, the correctness, practicability and reliability of power supply system as well as the digital control algorithm...

Jun 21, 2016 · This paper proposes a new magnet power supply for high-current magnets. The proposed system integrates a switch-mode ripple regulator with a phase-controlled rectifier.
Power supply & magnet optimization The powering optimization plays with the magnet parameters, the power supply parameters and the circuit layout. For the same integral field, the magnet can be done in different ways. The magnet parameters are: - Number of turns per coil N - Maximum current I - Current density in the conductor J
In this case, we have designed several new magnet power controllers for high-precision quadrupole and sextupole magnet power supplies and fast-correcting magnet power supplies. And...
