Coupled-Inductor Magnetics in Power Electronics
1987Leakages are inseparably associated with magnetic circuits and are always thought of in three different negative ways: either you have them and you don't want them (transformers), or you don't have them but want them (to limit transformer short circuit currents), or you have them and want them, but you don't have them in the right amount (coupled ...

Coupled-Inductor Inversion, Rectification and Cycloconversion
1986A new PWM approach using three state switching of negatively coupled inductors can be applied to any basic dc-to-dc converter to form single-phase dc-to-ac inverters. Current reference programming gives improvements in linearity, small-signal dynamics, and pulsed-load response. The current programming loops of the flyback and boost inverters are stable

Coupled inductor, constant resistance, broadband delay filter
Analog Integrated Circuits and Signal Processing, 2007This paper develops a three-terminal delay filter whose topology is an interconnection of only ideally lossless, coupled inductors and capacitors. In the absence of significant capacitive loading at the input and/or output ports, the proposed filter emulates an allpass network whose low frequency delay is twice that afforded by the poles of the ...

Coupled-inductor multi-phase buck converters [PDF]
, 2016 In a multi-phase power converter, efficiency is increased and ripple reduced while maintaining transient response and dynamic performance improved by electrically coupling secondary windings of transformers or provided for inductors of respective phases such that current to a load is induced in each phase by current in another phase.

Reduction of proximity losses in coupled inductors
IEE Proceedings B Electric Power Applications, 1991The authors present an investigation into the leakage fields and eddy current losses in the windings of inductors and coupled inductors used in high frequency applications. They show that the eddy current losses in the windings can be reduced significantly by the use of distributed airgaps, and that under these conditions the leakage fields are ...
