Modeling of high-frequency micro-transformers

IEEE Transactions on Magnetics, 2004
A dynamic model has been developed to predict the efficiency of a micro-transformer, operating at 5 MHz. The model includes a core hysteresis model, core eddy current model and winding copper loss model. Measurements and finite element analysis were carried out in order to validate the model.

High-frequency planar power transformers

IEEE Transactions on Power Electronics, 1992
High-frequency transformer design using the transmission line transformer (TLT) is described. Utilizing transmission line circuit theory, the characteristics of the TLT for different turn ratios are given, and its advantages, including its wideband nature, are discussed. TLT prototypes with turn ratios of 2:1, 3:1, and 5:1 were designed and fabricated.

High-frequency power transformer modeling

2013
The detailed study of high-frequency over- voltages propagating inside the electrical systems of a power plant requires a precise modeling of power transformers at high frequencies. These over- voltages may originate from lightning overvoltage propagating along the transmission line and crossing the step-up transformer, they may originate also for ...
