In this work we have developed and implemented on VHDL-AMS a model of the PiN diode, based upon the bond graph energy-flow modelling and the regional hypothesis. The PiN diode model is an association of several semiconductors region models. Each region is described by its important physical mechanism and the energy flow transfer between these regions is described by the bond graph paradigm. The primary...
A new experimental set-up is developed and validated to characterize high voltage diodes in switch transient regime. Parameters extracted from DMTVCA and OCVD techniques is validated in a buck converter on a resistive load. The experimental set-up enable to measure nice current and voltage transient characteristics, i.e. without noise and high parasitic wiring influence. Experimental results are confronted...
This prospective study assessed, in 10 conscious patients without a history of chronic respiratory disease, the feasibility of mechanical pressure support ventilation with PEEP by face mask for the treatment of acute respiratory failure without hypercapnia. Pressure support level was determined to obtain a VT of 5 to 10 mL.kg -1 and a decrease of respiratory rate of more than 20%. FIO...
