Bel group company Signal Transfomer has announced its new Wireless Charging Transmission Coils (WCC) in both Single and Multiple Windings for smart car applications ... They come in two core shapes, ...

The mutual coupling between the two transformer windings is not ideal but has a coefficient of 0.98. This coefficient represents the efficiency of the magnetic coupling between the two coils ... where ...

and reveals the distribution law of the induced electromotive force on the transformer windings. It is verified that the induced electromotive force is only concentrated in the part surrounded by the ...

Loading capability of power transformers is limited mainly by winding temperature. As part of acceptance tests on new units, the temperature rise test is intended to demonstrate that, at full load and ...

Abstract: A transformer winding method which can realize an adjustable turns ratio is proposed. In this paper, the LLC resonant converter is taken as an example, where the full-bridge (FB) LLC ...

Capacitance in a transformer winding cannot be avoided. The voltage difference between turns, between winding layers, and between windings to core, create these parasitic elements. In general, part of ...

Many dielectric and mechanical failures in large power transformers are preceded by mechanical changes in the winding structure. These changes, or displacements in the winding structure, may be the ...
