89888Power supply caps
- Apr 2, 2008I'm building a power supply and have a question on cap size.
My toroidal transformer will supply 40V at 24A. Now, according to the
standard cap formula, I would need roughly 30K-uf to sustain the 55VDC at
20A (derated to 80%).
My question is why none of the over-the-counter power supplies in this VA
bracket seem to use so much capacitance? Is this really overkill or are
they just cutting corners?
