Flyback converter turns ratio
WebQ4: In a regulated flyback converter with a 1:1 turns ratio, Vo = 12 V and Vd = 12 – 24 V, Po = 6 60 W, and the switching frequency fs = 200 kHz. Calculate the maximum value of the magnetizing inductance Lm that can be used if the converter is always required to operate in a complete demagnetization (equivalent to DCM). Assume ideal components [2]. WebThe calculated maximum Np2s is 1.45. The transformer used in the example has 12 primary turns and 10 secondary turns giving an Np2s of 1.2. After selecting the turn’s ratio it should be verified the 40-Vinternal MOSFET of the TPS55340 is sufficient for the voltage stress in the design. In a flyback topology the drain-
