This paper introduces a novel tunable inductor whose inductance can be adjusted continuously in a large range. The new inductor has one winding wrapped on a magnetic flux valve (MFV) and two C-cores attached to each side of the MFV to form a closed magnetic circuit. Its inductance can be altered continuously by applying an external control voltage on the MFV. This paper presents the concept, configuration,...
This paper introduces a voltage-controlled static magnetic device called magnetic flux valve. It is mainly used in a magnetic circuit to actively control the magnetic flux through the magnetic circuit. The magnetic flux valve has a laminated structure of two different types of layers made of a magnetostrictive material, e.g., amorphous alloy ribbon, and a piezoelectric material, e.g., piezoelectric...
