Generally, for a VSC-HVDC system, there are three control modes: a) constant DC voltage control; b) constant DC current or active power; c) constant AC voltage control (Asplund, 2000; Flourentzou, Agelidis et Demetriades, 2009; Sood, 2004). In mode a) and...
Fundamentals of DC/DC converter DC to DC converters are ubiquitous, from consumer electronics to electric vehicles. Such electronic devices often have multiple sub-circuits with their own supply level requirements different from the main input power which is either a built-in...
RT simulation offers several advantages to speed up the development of new product. One of these advantages being the possibility to test and develop controllers when the hardware is not yet available. This is a serious advantage in the case...
Télécharger le fichier original (Mémoire de fin d'études) The Scanning Tunneling Microscope The first technique to reproducibly achieve atomic-size contacts was the Scanning Tunneling Microscope (STM) with which even a controlled atomic switch has been operated [3]. Presently, the widespread...
Magnetic remanences The natural remanent magnetization (NRM) was measured on u-channel samples using a 2-G Enterprises Model 760R cryogenic magnetometer at 1 cm intervals. However, due to the finite spatial resolution of the pick-up coils (half-width of the response function...
Impact damage Impact damage is categorized into low-velocity impact damage (LVID) and high-velocity impact damage (HVID). The low-velocity impact is caused by quasi-static force, the higher limit of impactor velocity ranging from one to a few tens of ms−1 depending...
