If the output voltage of a DC/DC converter has 2 filter caps, 22u and 47u..22u connected to the inductor while the 47 connected to the output(22u and 47 u are in parallel connection). where is the best practise to probe the AC output ripple? will I expect the same results if I probe the caps with respect to ground? or I should proble the Vout load with respect to ground?
