Comparative Analysis of 72 Flyback Transformers on 5τ Non-linear Battery
with Loss Functions - Part III
Abstract
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.
