This is the final part of the three part series paper where the novel idea of representing flyback transformer losses as loss functions using hyperbolic secant spline interpolation,determination of the flyback transformer core saturation and instability in the control feedback loop from the loss function using Lyapunov method has been presented with scientific proof and validity. In this paper, the comparative analysis of 36 different flyback transformers from 30W to 85W is being presented.These two-winding transformers are operated in continuous/discontinuous mode,switched from MOSFET controlled by microcontroller from 60 kHz to 97 kHz. Eighteen wattage’s which are used internationally at different voltage and current ratings have been analyzed on fifteen different cores - EEL22, EE25, EEL25,EF25, EE28, EER28, EER28L, EE35, RM8/I, ETD29/16/10,ETD34/17/11, E25/13/7, PR30x19, ATQ27/18, RM12/I.
