Transformer design considerations for noncontinuous mode, boost, flyback converters [PDF]

Proceedings:Electrical Electronics Insulation Conference and Electrical Manufacturing & Coil Winding Conference, 2002
This paper presents some design considerations for small, flyback transformers used to charge energy storage capacitors from 0.1 to 5 kV from a low voltage DC source. The transformer has two roles: to act as an energy storage device, and to ratio the primary to secondary voltages.

Echo‐Planar‐Based Time‐of‐Flight Imaging Using a Modified Interleaved Flyback Trajectory

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3131-3144, June 2026.
ABSTRACT Purpose A modified interleaved flyback (miFB) approach is introduced, designed to mitigate flow artifacts caused by alternating readout polarities in Echo Planar Imaging (EPI), while preserving acquisition efficiency. Methods We propose reconstructing odd and even echoes of 3D‐EPI separately.

Highly Reproducible, Vendor‐Agnostic, Motion‐Insensitive Liver PDFF Mapping at 0.55T, 1.5T, and 3T

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2797-2813, May 2026.
ABSTRACT Purpose To develop and validate a vendor‐agnostic, motion‐insensitive proton‐density fat‐fraction (PDFF) quantification method. Methods Flip‐angle‐modulated (FAM) 2D chemical‐shift‐encoded (CSE) MRI for PDFF quantification was implemented in both the vendor‐agnostic platform Pulseq (“Pulseq‐FAM”) and one vendor‐specific platform (“GE‐specific ...

A Flexible Approach for Fat‐Water Separation With Bipolar Readouts and Correction of Gradient‐Induced Phase and Amplitude Effects

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1462-1477, March 2026.
ABSTRACT Purpose To develop a fat‐water separation approach that corrects bipolar readout gradient‐induced effects without additional scans and is compatible with any fat‐water separation method. Theory and Methods The proposed approach combines joint fat‐water separation of the odd and even echoes of a bipolar multi‐echo gradient echo acquisition with
