The second column indicates the time required for each segment, designed according to actual needs; the third and fourth columns are the starting and ending current values ​​for a certain segment, respectively, ensuring that the ending current of the previous segment is consistent with the starting current value of the next segment, thus achieving continuous output of current for each segment.

8. An electronic device, characterized in that, include: A processor and a memory, the memory being used to store computer program code, the computer program code including computer instructions, wherein when the processor executes the computer instructions, the electronic device executes the method of a modular scanning power supply capable of outputting segmented special current waveforms as described in claim 7.

9. A computer-readable storage medium, characterized in that, The computer-readable storage medium stores a computer program, which includes program instructions that, when executed by a processor of an electronic device, cause the processor to perform the method of a modular scanning power supply capable of outputting segmented special current waveforms as described in claim 7.
