| Abstract: | To meet the high steady-state accuracy, high voltage and high current performance requirements of the power supply for the ITER sensor test steady-state platform, the high power supply is designed with H bridge cascaded carrier phase shifting method. Meanwhile, harmonic analysis is carried out, which can effectively improve equivalent switching frequency of converter and improve output waveform. The supply has been verified by experiments and achieved good results. |
