This study develops a pulse‐width modulation (PWM) method that is referred the optimised
active harmonic elimination (AHE) technique to eliminate more harmonics with minimum …

The nacelle weight reduction is a key design criterion for offshore wind turbines, when these
are reaching towards 10 MW. To overcome the weight challenge, a transformer-less concept …

The size of offshore wind generators is increasing, and the trend is moving towards full
converter gear-less solutions with permanent magnet synchronous generators (PMSG). The …

Multilevel converters have seen an increasing popularity in the last years for medium-and
high-voltage applications. The most popular has been the three-level neutral clamped …

Pumped storage hydropower plants (PSHP) are widely used for bulk energy storage around
the world. The variable speed operation of these plants further enables their capability to …

Offshore wind farms are facing challenges which call for redesigning the electrical drive train
of future wind turbines. The turbines are expected to increase in power, and plans for 10-15 …

In this work, a STAtic synchronous COMpensator (STATCOM) with energy storage system
for wind power application has been treated. This device was proposed as a mean to …

The goal of the master thesis is to design, dimension and construct a power boost system for
the drive trains in electric vehicles, utilizing supercapacitor technology. In order to build the …

Les onduleurs multiniveaux sont très utilisés dans les applications de fortes puissances du
fait de leur capacité à générer une très bonne qualité des formes d'ondes, en réduisant la …

Multilevel converters have emerged as the state of the art high power conversion for
applications in reversible power flow. Electric power could be tapped from or injected to the …
