Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to a high-current inductor for two-phase voltage regulation. Background Art

[0002] Inductors mainly function to stabilize current and store energy in circuits, and are usually used in combination with capacitors. Through energy complementation and the alternating conversion between magnetic field and electric field, the two achieve the purpose of stabilizing voltage and current.

[0003] In traditional circuit design, the transient response in the circuit relies on the cooperation between the inductor and the output capacitor bank, while the output filter inductor prevents the fast rise from the voltage regulator. Moreover, currently commonly used capacitors are generally polymer capacitors, which will degrade during continuous use, affecting the service life of the capacitors and further affecting the stability of circuit output. Contents of the Utility Model

[0004] In view of the problems existing in the prior art mentioned above, the utility model provides a high-current inductor for two-phase voltage regulation, which can form two symmetrically arranged secondary windings and two primary windings on the two-phase inductor. After the two wire windings are energized, the two primary windings can generate mutual inductance with one secondary winding respectively, and generate corresponding current and voltage on the corresponding secondary winding, so that voltage output conversion can be realized without providing an output capacitor in the circuit, simplifying the circuit structure and improving the transient response of fast loads.

[0005] To solve the above technical problem, one technical solution adopted by the utility model is as follows:

[0006] A high-current inductor for two-phase voltage regulation comprises a first magnetic core and second magnetic cores symmetrically fixed at two opposite ends thereof.

[0022] refer to Figure 1-2 A high-current inductor with two-phase voltage regulation includes a first magnetic core 10 and second magnetic cores 20 symmetrically fixed at its two opposite ends. A copper sheet winding 30 and a wire winding 40 are provided between the first magnetic core 10 and each of the second magnetic cores 20. Each wire winding 30 is wound on the first magnetic core 10. Each copper sheet winding 40 is located around the first wire winding 30. The two copper sheet windings 40 and the wire windings 30 are symmetrically arranged on both sides of the first magnetic core 10. The two ends of the two copper sheet windings 40 and the wire windings 30 are located on the same end face of the high-current inductor.

[0023] During operation, the first magnetic core 10 and the second magnetic cores 20 on both sides thereof form a closed magnetic field. The two copper sheet windings 40 constitute the primary winding of the two-phase inductor, and the two wire windings 30 constitute the secondary winding of the two-phase inductor. After the wire windings 30 are energized, mutual inductance is generated with the primary winding formed by the copper sheet windings 40, and corresponding current and voltage are generated on the corresponding secondary winding, so that voltage output conversion can be realized without providing an output capacitor in the circuit, which simplifies the circuit structure and can improve the transient response to fast loads.

[0024] In some embodiments of the present utility model, the first magnetic core 10 has a centrosymmetric "I-shape with three horizontal bars" structure, comprising a first portion 11, a second portion 12 and a third portion 13 which are parallel to each other and arranged in sequence, and the ends thereof facing the same direction are all fixed to one second magnetic core 20 by adhesive. The second magnetic core 20 is a flat plate structure and is bonded to the ends of the first portion 11, the second portion 12 and the third portion 13 by epoxy resin.

[0025] In the above embodiment, each of the wire windings 30 has a "C" shape structure and is wound around one end of the second portion 12, and the opening direction thereof is all arranged on the upper end surface or the lower end surface of the first magnetic core 10. In this embodiment, each of the wire windings 30 is wound from a flat wire.

[0026] In the above embodiment, each of the copper sheet windings 40 has a "several" shape structure, covers the periphery of one wire winding 30 and is embedded on the first magnetic core 10, and both ends thereof are arranged outside both sides of the open end of the wire winding 30.

[0027] In other embodiments of the present utility model, two clamping grooves 14 are provided at the end of the second portion 12 facing away from the open end of the wire winding 40, each clamping groove 14 is fittingly embedded with one wire winding 30 and one copper sheet winding 40, and each copper sheet winding 40 is fittingly embedded between the first portion 11 and the third portion 13.

[0028] It can be understood that the clamping grooves 14 provide an embedding space for the installation of the wire windings 30 and the copper sheet windings 40, and cooperate with the second magnetic core 20 to ensure that the primary winding and the secondary winding on the inductor always maintain a stable state. During assembly, firstly, the two C-shaped wire windings 30 are respectively sleeved from the outer side of the second portion 12 and clamped into the clamping grooves 14, then the copper sheet windings 40 are sleeved on the outer side of the wire windings 30, the conductive ends of the two wire windings 30 and the two copper sheet windings 40 are all arranged on the end surface of the first magnetic core 10 facing away from the clamping grooves 14, and finally the two second magnetic cores 20 are respectively bonded and fixed to the two ends of the first magnetic core 10, so that the wire windings 30 and the copper sheet windings 40 can be fixed on the first magnetic core 10, and the assembly of the two-phase inductor is completed. In application, in order to ensure the stability of assembly, the widths of the clamping grooves 14, the wire windings 30 and the copper sheet windings 40 should be the same.

[0029] This invention establishes a first magnetic core 10 and two symmetrically arranged second magnetic cores 20 on opposite ends of a two-phase inductor. A wire winding 30 and a copper sheet winding 40 are respectively arranged between the first magnetic core 10 and the second magnetic core 20. This allows for the formation of two symmetrically arranged secondary windings and two primary windings on the two-phase inductor. When the two wire windings 30 are energized, the two primary windings can mutually induct with the primary windings, generating corresponding currents and voltages on the corresponding secondary windings. Thus, voltage output conversion can be achieved without setting an output capacitor in the circuit, simplifying the circuit structure and improving the transient response of fast loads.

[0030] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
