Investigation on the Parasitic Capacitance of High Frequency and High Voltage Transformers of Multi-Section Windings [PDF]
IEEE Access, 2020 Resonant converters are widely used in high voltage applications thanks to the soft switching technologies. The high frequency and high voltage (HFHV) transformer is the most complicated and important part to boost the voltage by tens or hundreds of times, and the parasitic capacitance of the transformers is critical to the performances of resonant ...

New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]
, 2014 For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase

Wave Phenomena in High-Voltage Windings of Transformers
Acta Physica Polonica A, 2014 Determination of mechanical condition of transformer active part can be performed utilizing frequency response of the windings. Many computing models were developed to evaluate behavior of the winding in wide frequency range using di erent numerical methods. Most of them utilizes nite elements, assuming axial symmetry, if possible.

Design of High Voltage Transformer Windings Withstanding Surge Voltages
IEEJ Transactions on Power and Energy, 1999 High voltage windings of high power transformers, have to be designed in such a way as to withstand surge voltages. From this point of view, interleaved windings have the better behaviour, but they are much more expensive with respect to continuous ones.
