WebCCM Flyback Transformer Turns Ratio Calculation (K = N S /N P) The transformer turns ratio can be calculated using the following formula: Where D MAX is the duty cycle assumed at minimum input (0.43 for the MAX17595/MAX17596). Primary Inductance Calculation Calculate the primary inductance based on the ripple: WebA flyback converter stores energy in the magnetic field in the transformer air gap during the time the converter switching element (transistor) is conducting. When the switch turns off, the stored magnetic field collapses and the energy is transferred to the output of the flyback converter as electric current.
