Este artigo descreve a evolução do conceito de segurança intrínseca utilizado para proteção de equipamentos elétricos em áreas com potencial risco de explosão como gases e poeiras combustíveis. Dentre outros tipos de proteção, a segurança intrínseca oferece um dos mais elevados índices de segurança em tais ambientes. O presente artigo tem como objetivo abordar sua evolução comparando os conceitos...
In this paper a model based in lumped elements is presented for the characterization of integrated inductors. The model allows the modelling of integrated inductors for a wide range of frequencies and different inductor topologies, thus granting the evaluation of important design parameters such as inductance, quality factor and self-resonance frequency. The model will be explained in detail and compared...
In this paper a general method for characterizing tapered inductors with square, hexagonal or octagonal shape is presented. The method proposed allows the evaluation of the series inductance to integrate in any integrated inductor lumped element model, thus granting the overall characterization of the device and the evaluation of design parameters such as the quality factor or the resonance frequency...
