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] The application relates to an electromagnet power supply and a method thereof, in particular to a digital dynamic electromagnet power supply with precise current control, a method and a digital controller for precise current control of a digital dynamic electromagnet power supply. Background technique [0002] With the development of digital control technology, the accelerator electromagnet power supply is developing towards the direction of full digital control. The static electromagnet power supply system of the accelerator, which is currently under construction or has been completed, has basically realized full digital control. However, in the dynamic electromagnet power supply with a repetition frequency of 10 Hz and above, there is no report on the use of fully digital control power supply technology. [0003] According to the investigation, at present, the excitation power supply of the dynamic electromagnet of the accelerator with a repetition ...
