Impacts of SiC-MOSFET Gate Oxide Degradation on Three-Phase Voltage and Current Source Inverters

open access: yesMachines, 2022
In this paper, the performance variations of SiC MOSFET-based voltage and current source inverters under gate oxide degradation are studied. It is confirmed that the turn-on and turn-off delays of SiC MOSFETs change significantly by high electric field ...

The Voltage Source Inverter [PDF]

open access: yes2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2019
This paper presents the Voltage Source Inverter. On this paper it will be discussed its topology, mathematical model, switching states and the characteristic curves of the inverter. Moreover, the authors will analyze the concept of “dead time”, aiming to understand how to correctly start a VSI without damaging its components.

A Novel Decomposition for Control of DC Circuits and Grid Models with Heterogeneous Energy Sources [PDF]

open access: yes, 2017
The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages

Measuring non-Gaussian fluctuations through incoherent Cooper pair current [PDF]

open access: yes, 2004
We study a Josephson junction (JJ) in the regime of incoherent Cooper pair tunneling, capacitively coupled to a nonequilibrium noise source. The current-voltage (I-V) characteristics of the JJ are sensitive to the excess voltage fluctuations in the ...
