In this video, I show how to set and measure the loop response of a discontinuous Flyback converter. I show how to validate the spice model, how to use Zero-Pole canceling to set the loop. I also show how to used the Bode 100 to measure the transfer function of the Output Filter, the Error Amp, and then take the Open Loop response.
