Inductors Murata for Transformers of Direct CurrentIn the present time working voltages of various range are used in the power circuits of the mobile devices. For this reason it is necessary to imply constant current transformers, converting the voltage of device supply into the nominal working voltage on each of these schemes. Non-isolated chopper heightening-lowering transformers are widely used for this purpose. The key component of these circuits is the power inductor. The losses thereon significantly affect the efficiency of the whole transformer. The wire inductors are screened in order to prevent the dispersing of the magnet current. In the components of the LQH production series Murata the structure with closed magnet induction is implied: the bundling is screened everywhere by epoxy resin with the magnet powder loading, preventing the dispersing of the magnet powder. The elements of this series have a simpler structure, than most of the power inductors presented on the market nowadays with closed magnet current on the basis of toroidal ferrite cores. Due to such construction in the LQH series throttles the bundling space is used to the maximum. This makes the construction more compact with smaller size and lower height. The maximum possible current of the wire inductor is determined through the parameters of the constant magnetization current. The latter, in turn, depends on the current inductivity parameter, varying with the temperature, depending on the ...
