In the frame of the European project UNIFLEX-PM, two AC/AC converter topologies hove been studied and implemented. Both converters, rated for 25 kVA, are isolated by a medium-frequency power transformer. The first topology is based on a dual active bridge ...
InAlGaAs/AlGaAs-based wafer-fused long-wavelength VCSELs with tunnel junction injection emitting in the 1310 nm and 1550 nm bands show high single-mode output and high speed modulation capabilities of 10 Gbps. Fundamental emission close to 6 mW at room tem ...

In the last years, static power converters have become widely used in various applications. They can be found in domestic applications, railways, urban and ship transport, and even in several industrial systems. Some of these applications require a high or ...
Many electric power generators use gas turbines as power sources. Typically they are connected to the turbines through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine, which is very often much hig ...
In the technology sector of power electronics and control, the multilevel converter technology is still a rather new research area, but the application possibilities in the field of power drives and energy will demand more solutions with this promising tec ...
For high power applications, multilevel topologies provide a number of advantages. In this paper, the single and three-phased multilevel converter is presented. Modulation methods and control schemes have been developed and tested on low-power prototypes. ...
A new surface micromachining method based on porous silicon formation followed by electropolishing is presented in this paper. It generates in a single electrochemical etch step a plate of porous silicon, releases it from the substrate without using a sacr ...
The paper describes the design of optimized PCB air-core toroids for high frequency DC-DC converters with strict requirements in terms of volume and noise. The effect of several design parameters on the overall inductor volume, on DC and AC winding resista ...
The initial commissioning of the 127 sectors of the LEP vacuum system requires local control facilities. On the scale of the LEP, local control of one sector implies the supervision of vacuum equipment which may be spread over 480 metres, with pump power s ...
