Chapter 6 of the Ultimate Guide to Flyback Transformer Design explains turns-ratio conventions, reflected output voltage, DCM/BCM/CCM volt-second balance, MOSFET and rectifier stress, demagnetization time, current transformation, auxiliary turns, integer turns, and a worked design comparison.
Chapter 5 of the Ultimate Guide to Flyback Transformer Design explains energy per switching cycle, magnetizing inductance, current ramp, peak and RMS current, DCM and CCM equations, tolerances, current-limit margin, and a worked design comparison.
Chapter 4 of the Ultimate Guide to Flyback Transformer Design explains how to define input, output, control, isolation, thermal, mechanical, EMI, manufacturing, tolerance, and optimization requirements before magnetic calculations begin.
Chapter 3 of the Ultimate Guide to Flyback Transformer Design explains DCM, BCM, and CCM current waveforms, mode boundaries, energy equations, magnetic bias, RMS current, semiconductor stress, control behavior, and operating-mode selection.
Chapter 2 of the Ultimate Guide to Flyback Transformer Design explains how energy is stored in the magnetizing inductance during MOSFET on-time and transferred to the secondary during off-time. It covers winding polarity, primary and secondary current waveforms, turn-off commutation, leakage energy, demagnetization time, volt-second balance, and a complete DCM switching-cycle example.
