On the integration of low frequency transformer into modular multilevel converter

Drazen Dujic, Alexandre François Christe

Various high power applications require power converters with large voltage step ratios, easily achieved by inclusion of a single or multiple transformers, which provide galvanic isolation at the same time. This paper presents, in a systematic manner, the ...

Broadly tunable source around 2050 nm based on wideband parametric conversion and thulium–holmium amplification cascade

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report the design of a short-wave infrared continuous-wave light source featuring a 20 mW average output power, and with a wavelength that can be freely selected in the 2000-2100 nm range amid a low power ripple. The operating principle relies on the si ...

Dynamic Analysis and State Feedback Voltage Control of Single-Phase Active Rectifiers with DC-Link Resonant Filters

Alfred Rufer, Michail Vasiladiotis

Single-phase active rectifiers exhibit an inherent strong second-order current harmonic on their DC-link. The latter is often undesirable from a load point of view and is therefore chosen to be eliminated. A common method is the use of a resonant passive L ...

Light spectral filtering based on spatial adiabatic passage

Victor Javier Cadarso Busto

We present the first experimental realization of a light spectral filter based on the spatial adiabatic passage technique. We demonstrate that a fully integrable CMOS-compatible system of three coupled identical total internal reflection silicon oxide wave ...
