I didn't know where to put this so I put it here  smiley-grin
A simple 1K resistor in series with a 33uf capacitor turns PWM into a pure wave!
Just wanted to tell everyone how easy it is.

Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.

Sorry but it is a bit more complicated than this. Using a simple RC filter is only a simple roll off filter and doesn't result in a "pure" wave.
