Sammendrag
This Master’s Thesis is established to design an optimal low-voltage high-power DC power supply
which can feed a biochemical system consisting of a microbial electrolysis cell, which further is
connected to an existing anaerobic digestion plant. The complete system is called a bioelectrochemical
system, where the purpose is to increase the amount of methane by reducing the amount of carbon
dioxide in the biochemical system.
The objectives for the thesis are mainly to design a power supply that can be used for a laboratory
scale setup. In addition, a minor evaluation of the scalability for a larger pilot setup will be performed,
as well as an investigation of the availability of commercial power supplies suitable for a laboratory
scale system.
There have been performed several methods to obtain the goal of the thesis, including a literature
review, and modelling and simulation of different power supply models in Simulink.
The thesis concludes that a switch mode DC power supply would be a proper choice to implement in
the bioelectrochemical system due to a high efficiency around 90 %, and with great regulation
opportunities. More precisely, the design of the half-bridge DC-DC converter with electrical isolation,
which had a series configuration, will be the recommended choice for an optimal low-voltage highpower DC power supply which can be connected to the biochemical system.

Power and domination in sport policy and politics: three intertwined levels of exercising power
Bergsgard, Nils Asle (Peer reviewed; Journal article, 2018)In this article, I discuss the fruitfulness of a three-level approach for studying power and domination in sport policy and politics, derived from the work of Pierre Bourdieu and Steven Lukes. This approach provides new ... -
Power Converters Dominated Power Systems
Gonzalez-Longatt, Francisco; Acosta Montalvo, Martha Nohemi; Chamorro, H. R.; Rueda Torres, Jose Luis (Chapter, 2020)The transition to a low-carbon society is the driving force pushing the traditional power system to increase the volume of non-synchronous technologies which mainly use power electronic converters (PEC) as an interface to ...
