This paper presents a novel architecture for wireless communication systems made up of a base station and a remotely powered transponder. The architecture enables the base station to perform wireless voltage regulation (WVR) of the rectifier's output volta ...
This paper is focused on the design, modulation and control of a re-generative non-symmetrical multi-level converter for high-power applications such as oil and gas or mining. The converter is based on standard IGBT modules and the DC-link voltages are cho ...
Spin-dependent transport properties of nanowires containing individual Co/Cu/Co pseudo-spin valves were investigated by monitoring an AC voltage induced by a temperature oscillation under a continuous DC current. We observed sharp peaks in the field-depend ...
The inner control of a Modular Multilevel Converter (M2C) must be designed so that the submodule capacitor voltages are equalized and stable independent of the loading conditions. It has been shown that a submodule selection mechanism, included in the modu ...
A new technique, Amplifier and Comparator Based Switched Capacitor (ACBSC) for low voltage switched cap circuits, is presented. ACBSC combines the recently introduced CBSC (comparator based switched capacitor circuit) with an amplifier. The current sources ...
Europe is currently making a great effort in order to improve the sustainability and reduce the environmental impact of its energy and transportation systems. A key role on these initiatives is played by efficient generation systems, like cogeneration, and ...
Many popular micropumps implement moving parts that presents serious drawbacks. This is one of the reasons for the growing interest in valveless micropumps. Pumps exploiting AC electric fields are investigated here. Theoretical results are recalled and the ...
Nowadays, the scarcity of cheap energy sources requires a particular effort in optimizing the performance of all conversions. The electric power vector is particulary expected to grow in importance, in conjunction with the development of renewable energy s ...
