(+) TIDM-02013: Regarding the boost issue of the PFC stage, the current does not follow the voltage, and the power factor is around 0.5. - 电源管理论坛 - 电源管理 - E2E 设计支持
Part Number: TIDM-02013
Hi,as shown in the figure,lab 1 to 4 are all aimed at verifying the PFC mode.
However, why did lab 1 and 2 use DC as the input, rather than AC voltage?

Hi ,
Wang Xuesong 说: Both Experiment 2 and Experiment 1 adopt current loop feedback regulation. However, Experiment 2 states that when the AC current reference (ac_cur_ref) is 0.045, the input current is 2.4 A; Experiment 3 describes that when ac_cur_ref…
