There do exist ceramic ones of big values like 10µF, 22µF, 47µF and even 100µF. Never ran into them in any commercial equipment tho (probably cause electrolytics are cheaper), but you can buy them.
Is reducing the ripple greatly below the tolerance levels useful in any applications?Once stability is achieved to a certain extent is there any use of further increasing the stability?In which applications does this make a difference?
I think there are two different things being discussed in this video: 1) the output ripple, and 2) the switching noise appearing in the output. What is actually is being reduced here by the addition of the ceramic capacitor is primarily the switching noise not the ripple.

VPT's engineer recommends 20uF = 2 x 10uF in parallel.

agree, the output ripple is predominately relying on the inductor thereof. but I do not fully understand how LC filter affect the transformer.
Thanks a lot for this video!
awesome thanks for this video. esp explanation of where to place low esr capacitors
You're very welcome!
Dear sir, Please can you provide formulas pr equation for calculating parameters for this designs. Perhaps I really liked this video over others...
Thank you for watching! Please see our website www.vptpower.com for more product information.
ceramic capacitor is picofarad right,..??
not a microfarad,...??
its pF not a uF
