Embodiment Construction

[0025] The following will combine Figure 1 to Figure 3 Describe this application in detail. It should be noted that in the drawings of the present application described below, elements or modules with the same reference number have the same function in the system; if there is a cross point between the line segments that are connecting wires or signal paths, then cross A black dot "·" on the point indicates that the intersection is a connection point or a signal branch point, and no black dot "·" on the intersection indicates that the intersection is not a connection point or a signal branch point but just crosses each other ; The coil shows a schematic diagram of the magnet load, and does not represent any parameter of the magnet load.

Abstract

An electromagnet power source comprises a digital controller, a modulator, a power device and an electric current transducer, wherein based on a preset referential current signal and a sensing current signal of output electric current corresponding to the electromagnet power source, the digital controller produces a controlling current signal, based on the controlling current signal, the modulator produces a power device controlling signal, based on the power device controlling signal, the power device draws electric energy from a power supply and provides an electromagnet load for the electric current, and the electric current transducer is arranged at the output end of the electromagnet power source to produces the sensing current signal. The electromagnet power source and control method and digital controller of the electromagnet power source provides a method used for controlling the electromagnet power source and the digital controller.

Description

Technical field [0001] This application relates to an electromagnet power supply and a method thereof, and in particular to a digital dynamic electromagnet power supply with precise current control, and a method and a digital controller for a digital dynamic electromagnet power supply for precise current control. Background technique [0002] With the development of digital control technology, the accelerator electromagnet power supply is developing in the direction of full digital control. The accelerator static electromagnet power system currently under construction or has been built has basically achieved full digital control. However, in dynamic electromagnet power supplies with a repetition frequency of 10 Hz and above, there has not been a report on the use of fully digital control power supply technology. [0003] According to the survey, the current accelerator dynamic electromagnet excitation power supplies with a repetition frequency of 10 Hz and above all use control te...
