BACKGROUND AND OBJECTIVE The measurement of breathing pattern in patients with chronic obstructive pulmonary disease (COPD) by electrical impedance tomography (EIT) requires the use of a mathematical calibration model incorporating not only anthropometric characteristics (previously evaluated in healthy individuals) but probably functional alterations(More)
This work is intended to describe a novel topology for a class E oscillator for induction heating in cooking applications. The topology is remarkable for low cost, low size and medium-high power applications where efficiency is a must. Experimental results for a 900W (92% efficiency) prototype are included. Multiple-burner induction cooking system including(More)
Keywords: Thermal limits 600 V–50 A RC-and Trench-IGBTs a b s t r a c t This work focuses on determining the switching limits in temperature for Reverse Conducting IGBTs and compares them to ''conventional'' IGBTs based on Trench technologies, all them belonging to 600 V–50 A application scenario. After, their leakage current under blocking state is tested(More)
OBJECTIVE Electrical impedance tomography (EIT) involves the application of a small alternating current to produce a series of chest images that can be used to monitor breathing pattern. The relation between chest images and tidal volume has not been sufficiently validated. The aim of the present study was to analyze the correlation between EIT images and(More)
