| Abstract: |
| Relative to the single-stage Boost PFC, interleaved Boost PFC designs hardware simply reduces the output ripple and has high power density. In this paper, the Boost PFC are analyzed in principle, including the working process, build the mathematical modeling with the state space averaging method, and the analysis of current ripple. Finally make a 4Kw Interleaved Boost PFC, and test the related parameters. |
