The compensator transfer function based on optocoupler feedback can be estimated with Equation 18: (18) The middle-frequency gain is formed in two stages: the optocoupler gain and the adjustable ...

Writing the transfer function in this form allows us to talk in terms of poles and zeros. Here we have a single pole at ωp = 1/ RC. While the 1-kHz output of the RC circuit (red trace) is the ...
