Energy Processing for Magnetic Coil Demagnetization

An energy processing system for a magnetic coil, comprising:

• an energy conversion system configured to:
• perform voltage or current regulation on electric energy of the magnetic coil during demagnetization of the magnetic coil, receive the energy of the magnetic coil in a nonlinear manner by collecting the energy of the magnetic coil with a low voltage first followed by a high voltage, and output electric energy with a stable voltage or a stable current that is adapted to an energy storage system,
• wherein the energy storage system is configured to accumulate and store the electric energy output by the energy conversion system;
• an energy release system configured to release electricity stored in the energy storage system;
• and
• a control system configured to:
• control the energy conversion system to perform energy conversion during the demagnetization of the magnetic coil;
• monitor the energy storage system, and when an amount of electricity stored in the energy storage system does not reach a set threshold, control the energy storage system to accumulate and store the electric energy output by the energy conversion system, and when the amount of electricity stored in the energy storage system reaches the set threshold or when a discharge instruction is received, control the energy release system to release the electricity stored in the energy storage system;
• and
• adjust discharge power of the energy release system,
• wherein nonlinear control of demagnetization speed is implemented by controlling a voltage at which the energy conversion system collects the energy of the magnetic coil and controlling the discharge power of the energy release system.
