WebJun 19, 2024 · This is great to determine the small-signal response of many switching circuits and not only a flyback converter of course. What is cool is that the subcircuit determines the operating mode itself and works for ac … WebDCM offers higher efficiency than CCM, due to the lack of reverse recovery loss on the diode and a softer turn on of the MOSFET. However, if the duty cycle is too small, then the current that charges the primary inductor will be very high, which lowers the converter’s overall efficiency. Thus, a reasonable duty cycle must be chosen for DCM to ...
