WebYou could use the CCM example and pretty much disregard the RHP pole. I would still calculate it, but in most applications it will be far away from the crossover frequency. Generally for non isolated topologies I suggest at least type IIB compensation which is a R+C in parallel with a C from FB to COMP. WebMar 29, 2024 · The square drain-source waveform is typical of the CCM operation for the flyback but also for many other converters (as the DCM ringing): and finally, there is a third possible case which is also DCM but optimized in such way that the switch always turns on in the minimum of the drain-source voltage. Webcompensation is much easier.
