I. Introduction
High-leakage transformers play an important role in power conversion in areas ranging from resonant conversion for dcdc applications to the separable-transformer based systems used in transcutaneous, marine, mining, and automotive power transfer [1], [2]. Outside these technical areas, transformer leakage can critically impact the operation of standard converters [3]–[5]. Thus, we are interested in quantifying the magnitude of the leakage parameters associated with the transformer primary and secondary windings. Characterization of these discrete leakages can be especially important for optimising the functionality, efficiency, and modelling of power converters using loosely-coupled transformers.
