typically , I believe domestic SMPS power supplies above 1kw do not come under power factor laws. This is because there just aren't any. But when EV chargers become extremely common, laws may change. Industry has SMPS's above 1kw, but they pay for their poor power factor, so nobody minds them not being power factor corrected. I have searched everywhere but can find nothing. I have emailed other companies who make ev chargers, but the replies come back from members of staff who obviously don't have a clue what power factor is. I had one reply which was hilarious.
Four years ago I worked for a guitar amp company, and we couldn't find out if guitar amps needed to be pfc'd, (there were posts on this and loads of other forums) I think the same "greyness" exists over EV chargers, its just not possible to find out.
Basically, we want to cheat and use our boost PFC stage as a straightforward boost converter, and not a slow bandwidth pfc stage. This is because we want to reduce the ripple voltage on the pfc output bus, because it will make regulation of the following LLC converter easier. So we want our boost pfc to not need to be fully PFC'ing the supply.
