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. WebFlyback Converter Design Process and Calculations Step 1: Design Inputs Design inputs are either defined by the end application or selected by the designer. These parameters include, but are not limited to, the input and output voltages, power, ripple factor, and operation mode.
