| Abstract: | This paper presents a 300A standard constant current source design that uses high stability DAC as the current output control and apply the technology of high-precision detection of zero flux DC current to realize current feedback.This constant current source has a DC current output capacity of 10~300A.Its maximum output power is 2400W.The maximum permittable error of output current is ±（5×10-4 set value ＋1 digit）,and the stability is 5×10-5/30 minutes. |
