| Abstract: | A digital design scheme for traditional bridged active power factor corrector（APFC） was implemented based on DSP TMS320LF2808 and the hardware circuit and parameter configuration were designed including high value silicon steel inductor and so on. DSP control program was made systematically, such as incremental digital PI regulator for current inner loop and voltage outer loop, digital divider, multiplier, filtering programs and so on. The designed APFC was tested, showing up to 5.0 kW in output power 95% in efficiency and very good correction effects. |
