>I recall that single-diode rectifiers are used in low-power SMPS designs
the isolated flyback converter is, roughly, what you get when you replace a boost converter's inductor with a transformer. the primary switch builds the magnetic field by gating power to the primary, the secondary winding(s) and their diode(s) accept the energy from the field's collapse

for a diode question? absolutely, fren
your latest replies show a better understanding than a few hours ago, I call it a strong 3. don't be disheartened, there are a LOT of subtleties in electromagnetics to know to get that perfect 10. my own understanding of electromagnetics is a solid 5 on a really good day
>he started the course assuming we knew about it
that's a bit of an ASSumption on his part, but I imagine it knocks out the ones who are absolutely lacking drive to research and explore independently. you, on the other hand, sound like a survivor
>Sorry, the word junction fucks me up.
I'll say "node" if that helps. waveform #3 is what you would see if you stuck a scope probe on that node where diode and cap meet. remove the cap and it's waveform #2. note that current only flows in the diode when the ac voltage exceeds that of the cap
>Thank you anon
no problemo. the hydraulic-electric analogy does work for the new student, but it's imperfect and shouldn't be taken too far

welcome to forever, anon
