WebThe CCM-DCM boundary transition is best seen by plotting for each circuit topology the following: duty cycle, D, on the ordinate or y-axis versus the ratio I Av(D)/I o(peak) on the abscissa or x-axis. We will get unique plots for the three major converters as shown below in anticipation of the results we will derive herein later. 1.0 1.0 WebFlyback is modulated at twice the mains frequency. This causes the spectrum to be spread over the wide frequency band than a single frequency values Given the benefits, there are also some drawbacks. Since this is still effectively a DCM Flyback, peak and RMS current remains higher compared to CCM Flyback.
