WebFeb 9, 2024 · For 2-sw forward it's limited to 50%. For DCM flybacks there's no theoretical limit since it's all about the volt-seconds balance but in practice it's better to keep it below 50% to guarantee a proper reset and for the sake of the primary switch's health (The higher the duty-cycle the higher the reflected voltage and thus the primary switch ... The flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage. There are three common ways to generate this voltage: 1. Use an optocoupler on the secondary circuitry to send a signal to the controller.
