very good explanation sir ji again... my question is that if an smps have three in one design means have three output sources like 5v,12v & 24v, does this type of smps have only one or same snubber circuit for all output???

[@SajjadAli-yd6dz]

Thanks sir app ki video dekhi app ne bohat ache tarike se samjhaya . sir app se aik sawal puchna tha . ke mere pas aik laptop ka 12 volt 9amp ka laptop ka charger he . me us se aek dc 12 volt 15amp ki motor chalana chahta hon . please meri help karein . ke motor bi chalti rahe our charger bi na kharab ho.
