Power supply energy optimization for ultra low-power wireless sensor nodes

Pierre-André Farine, Alexis Boegli, Mitko Tanevski

The wireless sensor nodes are most energy-efficient when they operate at the minimal operating voltage. The nominal voltage of the batteries used is often significantly higher. This paper analyzes DC-DC power conversion from the point of view of ultra low- ...

Operation of Modular Multilevel Converters Under Grid Asymmetries

Alfred Rufer, Michail Vasiladiotis, Daniel Siemaszko, Nicolas Cherix

The Modular Multilevel Converter is very likely to operate in a grid-connected mode under asymmetric conditions. Such a converter features several unique characteristics, which make its analysis different from other types of power converters in similar cas ...

A DC power flow extension

Maher Kayal, Theodoros Kyriakidis

In this work an extension of the well-known DC power flow method is presented. A normal DC power flow of the system is executed to determine voltage angles and a novel derivation of voltage amplitudes is devised. The latter is rigorously formulated and eig ...

Characterization of a 6.5kV IGBT for medium-voltage high-power resonant DC-DC converter

Drazen Dujic

Medium-voltage (MV) high-power converters are usually realized using high-voltage semiconductors (3.3kV, 4.5kV or 6.5kV) operated with low-switching frequencies in the range of several hundred Hz and under hard-switching conditions. However, for medium-vol ...
