| Abstract: | The input power,system efficiency and load capacity are more.A constant-current voltage-stabilizing SMPS is analyzed and designed with single-phase AC voltage input,0~55V output voltage range,0~100A output current range and input PFC.The pre-stage employs interleaved paralleling APFC,the post-stage employs full-bridge inversion,step-down transformer and full-bridge rectification.The high-frequency switch transformer is designed with quasi-resonant soft-switching technology at primary part.The experimental results show that the output characteristics of the constant current voltage-stabilizing SMPS with interleaved paralleling APFC are good,and the system efficiency is improved. |
