In design of high-frequency magnetic devices, various approaches have been used to provide calculation tools that are able to predict winding losses, including skin effect and proximity effect, in their two-dimensional (2-D) aspects. Up to now, these

SummaryThe 3-levelvoltage inverter is an efficient solution for high power variable speed drives, as it combines high voltage capabilities(due to GTOs in series)and significant reduction of losses and/or switching frequency(due to the intermediate le

The application of three-level pulsewidth modulation (PWM) to voltage source inverters feeding three-phase induction motors is considered. A subharmonic modulation method using two modulating waves is introduced. It is particularly well adapted to th

An improved current-injected modelling method is used to obtain in an easy but accurate way the transfer functions of a DC-DC converter controlled by output equalization. The approach has been used to develop an output voltage regulator with a near-o

This paper proposes an analysis of copper losses within a classical winding structure of power transformer (copper foil on secondary side). A model of such a structure with a semi-empirical formula, enhanced by 2D-finite element simulation, leads to

Magnetic components play an important role in the technological evolution towards increased power density of AC/DC power converters. Planar transformers provide several advantages that have to be balanced with the latest evolution of more classical t
