| Abstract: | A strategy of hybrid precise current source was proposed in this paper,which combined the advantages of switching power and linear power with excellent waveform,high efficiency and small volume.DSP was used as the core of control system,so the system was precisely,reliably and digitally controlled.The result of experiment shows that the current source has good waveform quality and low THD,which proves the effectiveness of the strategy. |
