Transformer capable of achieving winding non-orthogonal decoupling

Abstract

The invention discloses a transformer capable of achieving winding non-orthogonal decoupling. The transformer capable of achieving winding non-orthogonal decoupling comprises a transformer winding and a non-orthogonal decoupling winding, wherein the transformer winding and the non-orthogonal decoupling winding are manufactured on the same iron core in a winding mode, and the non-orthogonal decoupling winding comprises series coils which are equal in number of turns in even number sections and opposite in winding direction. According to the transformer capable of achieving winding non-orthogonal decoupling, the non-orthogonal decoupling theory is applied to decoupling between specific windings of electrical devices such as the transformer in engineering, that is, only magnetic coupling exists and powerless coupling does not exists between a certain pair of windings or certain pairs of windings through a specially-designed winding distribution mode. Due to the fact that decoupling can be achieved in the non-orthogonal arrangement mode, compared with orthogonal decoupling, the size of the devices can be effectively reduced, and the utilization rate of manufacturing materials is improved.

Description

technical field The invention relates to the field of electromagnetic fields, in particular to a transformer capable of realizing non-orthogonal decoupling of windings. Background technique According to the electromagnetic field theory, a magnetic field is generated by an electric current, that is, if a current is passed through a conductor, a corresponding magnetic field will be generated around the current-carrying conductor. In practice, current-carrying conductors are often wound in the form of coils (windings), and the physical phenomenon that these coils are interconnected by their respective magnetic fields is called magnetic coupling. For some of the two current-carrying coils, if power can be transmitted from one coil to the other, it is said that there is power coupling between them, and such coils are called coupled coils. Coupled inductance is a circuit model abstracted from the actual coupling coil, which reflects the phenomenon that the magnetic flux and magn...

Problems solved by technology

In a multi-winding transformer, in order to realize the electromagnetic decoupling of one winding from another winding, they need to be placed vertically, which requires a special core design so that the two windings are arranged orthogonally, or by extending the iron The core magnetic circuit reduces the coupling factor by increasing the reluctance. However, both methods will increase the size, weight and cost of the transformer itself, which is not conducive to engineering application and promotion.
