Embodiment Construction

[0026] figure 1 It is a schematic diagram illustrating an inductance device 100 according to an embodiment of the present application. figure 2 According to an embodiment of this case, a kind of figure 1 An enlarged schematic diagram of part of the circuit 170 of the medium inductance device. see also figure 1 and figure 2 , in an embodiment, the inductance device 100 includes at least two coils (such as coils 130 and 140 ) and at least two switches (such as switches SW1 and SW2 ). Each of at least two coils (such as coils 130 and 140 ) includes openings (such as openings 131 and 141 ) corresponding to each other (such as openings 131 and 141 are disposed on the upper side of the inductive device 100 and are adjacent to each other). One of the at least two switches (such as the switch SW1) is coupled to the two ends of the opening of one of the at least two coils (such as the two ends 132, 133 of the opening 131 of the coil 130), and the other of the at least two switche...

Abstract

The invention discloses an inductance device. The inductance device comprises at least two coils and at least two switches. Each of the at least two coils comprises an opening, and the two openings correspond to each other. One of the at least two switches is coupled to both ends of the opening of one of the at least two coils, and the other one of the at least two switches is coupled to one end of the opening of one of the at least two coils and one end of the opening of the other one of the at least two coils in a staggered manner. If one of the at least two switches is switched on, one of the at least two coils forms an inductance; if the other one of the at least two switches is switched on, the at least two coils together form an inductance.

Description

technical field [0001] This case relates to a basic electronic component, and in particular to an inductive device. Background technique [0002] Various existing types of inductors have their own advantages and disadvantages, such as spiral-type inductors, which have a high quality factor (Q value) and a large mutual inductance value (mutual inductance), but its Both the mutual inductance value and the coupling occur between the coils, and for the figure-eight inductor, because the two coils induce the magnetic field in the opposite direction, the coupling and mutual inductance value occur in the coupled magnetic field of the other coil. In addition, the figure-eight inductor The area occupied by the device is relatively large. Therefore, the scope of application of both is limited. Contents of the invention [0003] A technical aspect of the present application relates to an inductance device, which includes at least two coils and at least two switches. Each of the at...
