Hello everyone, sorry if I sound stupid with such question but I studied time ago rectifiers with high power factors that emulate variable load after graetz bridge to reduce current harmonics number. They use buck boost or fly-back converters for that. Are these implementations even popular in commercial devices?
Where are they used? Do they already use them in new generation battery chargers for mobile phones? Or in some particular applications? I think such a type of system is efficient but has a higher cost than classical simple graetz rectifiers with ICs like 7805 because there's also a control part and duty cycle generation etc ...
Please tell me anything you know about it, I would appreciate it...
