Analysis of the Distributions of Displacement and Eddy Currents in the Ferrite Core of an Electromagnetic Transducer Using the 2D Approach of the Edge Element Method and the Harmonic Balance Method

Autor: Wojciech Ludowicz, Rafał M. Wojciechowski

Publikováno v: Energies, Vol 14, Iss 13, p 3980 (2021)

The negative impact of the displacement currents on the operation of electromagnetic converters results in additional losses and faster insulation degradation, as well as the self-resonance phenomenon. Effective measurement of the dielectric displace

The wide range of output frequency regulation method for the inverter using the combination of PWM and DDS

Autor: Wojciech Ludowicz, Wojciech Pietrowski, Rafał M. Wojciechowski

Publikováno v: COMPEL - The international journal for computation and mathematics in electrical and electronic engineering. 38:1323-1333

Purpose The specific modulation methods are used to control different kind of single-phase, as well as three-phase, inverters to ensure flexibility and high quality of the output waveform. This paper aims to present a combination of two classical met

Project of a universal inverter used to control and supply both AC and DC electric motors

Autor: Wojciech Ludowicz, Rafał M. Wojciechowski, Dawid Danielczyk

Publikováno v: ITM Web of Conferences, Vol 28, p 01018 (2019)

The paper presents the new approach for motor driver constructions and control systems. Authors of the work proposed the device that can control both AC and DC electric motors without any additional hardware modification. In order to meet this goal t
