Hello,
I'm a PhD student and i would like some information from you. I work on the susceptibility of power supplies of electronic equipments at home (TV, internet box, notebook, mobile phone, computer ...). (AC/DC)
I made some researches and I found it existes differents topologies. Nowadays, I think switched mode power supplies are the most used and it existes "flyback", "forward", "half-bridge" and "full bridge" power supplies and theirs versions resonant or quasi-resonant. I also found "flyback" power supplies are used under 100W, "forward" between 100 and 300W, "half-bridge" between 300W and 1500/200W and "full-bridge" above theses powers. I think linear power supplies are less used today.
For confirm these boundaries, I collected datasheet about power supplies evaluation board on the Internet. Finally, I can conclu that power supplies are type of "flyback" or "quasi-resonant flyback" between 0 and 70W and "half-bridge resonant LLC" between 90 and 500W. Therefore, boundaries that I found before are not correct.
I contact you to have your feedback about my researches whose I told you before. Does a conclusion may be extracted to know what type of power supply is used according to the power ? Moreover, have you got some information about this subject which could be interesting for my bibliographic part ? Have you got some topolgies which could be representative of the most of power supplies in home appliance ?
For all explain to you, I am at the beginning of my thesis and I try to find which kinds of power supplies are used at home and which kinds of topologies are used. The goal is to select two or three topologies which could be representative of power supplies which we could find at home in order to make experiments on them.
Thank you in advance for your answer which will be very important for me and sorry for my English, which can sometimes be rough.
Guillaume
