Traditional boost PFC are suggested to be under 4kW with >180VAC input voltage, if the input voltage is even lower or the power rating >4kW, suggest to design with interleaved boost PFC topology, to reduce the current stress and power loss…
since each PFC inductor need to cover full load at one half main line cycle, so the peak current through each inductor is almost two times compare to interleaved PFC mode. For the peak current requirement, you need a bigger size for PFC inductor…
PMP4311 is very old reference design, there is no such data you required. There is another 800W reference design PMP40261, there are ITHD data for different input voltage and output load. here is link of PMP40261. BTW, PMP40261 is bridgeless…
thanks for your interest in UCC28070, you need more Xcap and input filter circuit for bridgeless PFC.
below is a link for an reference design about this application.
There is reference design PMP40261 for UCC28070, the schematic and layout is based on Altium designer. You can download design files in below link.
if you look at Vinac and AC voltage, there is a very high spike during the current distortion, please double confirm why there is a spike here.
unfortunately I can see clearly the schematic after zoom in.
in the datasheet page 21 at paragraph…
Other Parts Discussed in Thread: PMP40261 , UCC28070 , UCC28180 , PMP9640 , UCC28051 , UCC28951 Hi,
Do we have PFC single phase dual boost bridgeless to propose to customer for new designs? Write also me in private for any roadmap we might have.
You might be able to get it to work in semi-bridgless; however, it will not in full bridge less PFC due to the lack of gate drivers and appropriate timing.
The UCC28070 has been proven work in bridgeless and there is a reference design…
