Experimental analysis of a DC current-controlled variable inductor in a DC-DC converter

Abstract: Estimados leitores Um pouco mais tarde que o habitual, pois os afazeres dos responsáveis pela edição da revista no fim de um ano letivo numa escola prestigiada de Engenharia são sempre muitos e complicados, voltamos à Vossa presença com mais uma edição da nossa revista Neutro-à-Terra. Estamos certos que a qualidade dos artigos publicados nesta edição seguramente que compensarão a curiosidade e o interesse de todos os nossos habituais leitores, que nos privilegiam com o seu interesse desde o início das nossas p… Show more

“…There are three main approaches utilized to control the relative permeability of magnetic cores: 1) current-controlled approach, and it is the most popular one that utilizes an external DC bias current to adjust the relative permeability of the magnetic core; 2) liquid-controlled approach, and it is the less popular approach that employs MEMS technology in conjunction with liquid fluids to alter the relative permeability of the medium, which represents the magnetic core in that case; 3) voltage-controlled approach, still-evolving technology that employs an external DC bias voltage to adjust the relative permeability of the magnetic core. The first technique is DC current bias, also known as actively current-controlled variable inductors, and is the most frequently utilized in power electronic converters, as discussed in [16], [20], [21], [22], [70], [71] , [72], [73], [74], [75], [76], [77] and [78]. While, the second and third approaches are less popular in power electronic applications.…”
