On a Future for Power Electronics
J. D. van Wyk,Fred C. Lee +1 more
TL;DR: In this paper, the fundamental functions found in electronic energy processing, the constituent technologies comprising power electronics, and the power electronics technology space in light of the internal driving philosophy of power electronics and its historical development are examined.
Journal ArticleDOI
Measurement and compensation of fictitious power under nonsinusoidal voltage and current conditions
Johan H. Enslin,J. D. van Wyk +1 more
TL;DR: In this article, a time-domain definition of power, using correlation techniques, is proposed to establish a method for fictitious power measurement and derive fictitious power compensation criteria in power systems with nonsinusoidal currents and voltages.
Proceedings ArticleDOI
Some considerations for miniaturized measurement shunts in high frequency power electronic converters
TL;DR: In this article, four different types of shunt constructions and installations are tested on the same power electronics circuit, giving widely diverse results, which will assist in developing accurate current measurement devices for fast switching transient power electronic converters of the future.
Journal ArticleDOI
A planar integrated RCD snubber/voltage clamp
TL;DR: In this article, an electromagnetic integrated resistor-capacitor-diode (RCD) snubber/voltage clamp is described and the performance is verified experimentally.
Proceedings ArticleDOI
Problematic aspects when using a LISN for converter EMI characterisation
TL;DR: In this article, it is shown that conducted interference from a power converter differs when measured with and without a Line Impedance Stabilization Network (LISN) This is problematic as the true Electromagnetic Interference (EMI) of a converter is therefore difficult to characterize.
