Is it reasonable/possible to build an 8 amp 20 V transformerless
power supply from a 120Vac line.
I calculate about 180uf plus or minus depending on other components.
Maybe 9- 20uf caps in parallel?
I'd like to build it into a leaf blower.
All plastic, absolutely no metal exposed.
I think I've answered my question, I have 12, X rated caps in my junk
box, but they are only 1uf.
The cheapest 20uf I can find is $3, so $27 for 9 caps. Not reasonable.
Just had another thought, I could mount a power supply with
transformer on the wall and have a cord go to the leaf blower. Just
trying to build a light weight Leaf Blower for the wife to clean the
garage once a week.
Daughter gave me the leaf blower after the battery charger gave up.
Input encouraged.
