   Disturbance Currents of Inverters
By Petr Vrana [View]
[Download]

Abstract: This paper presents a research on a DC-AC (AC-AC) inverter used in a locomotive drive. The research is focused on creation of harmonic currents in DC-link. The content of some harmonics is restricted by standards and we call such harmonics as disturbance currents. The goal of this research is to found effects which are adherent to disturbance currents and on the basis of this to implement the changes of the power circuit, the control algorithm and the modulation.

   Potential of Digital Gate Units in High Power Appliations

Abstract: Gate units of today's converters are in most cases voltage sources charging the input capacitance with a fixed gate resistor. Consequently, there is hardly no possibility to adapt quickly the gate unit to different semiconductor devices. During operation, there is no adaption process to adjust the switching transients to their actual optimum. The possibilities to implement new features or to adapt the units for a different device are related to time and effort. Therefore, in this paper the idea of a digital gate unit is explained and presented.
