Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The transformer, drive circuit system and electronic equipment of the present invention will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the implementation can be combined with each other.

As shown in Figures 1 and 2, the transformer includes a support 10 and at least two sets of winding groups 20 surrounding the support 10. The surrounding centerline of each of the winding sets 20 is perpendicular to the remaining windings. Circle centerline of group 20.

The support 10 may be a rigid structure, and the winding group 20 is fixed to the support 10 around the support 10 in a corresponding winding manner. Each winding group 20 constitutes an approximately ring structure and has a surrounding centerline. For example, the circular cross section formed by the winding group 20 on the support 10 is similar to a circular ring, a polygonal ring structure, and other ring structures. Each winding group 20 has a vertical structure in space. Correspondingly, in the case of energization, the directions of the magnetic fields generated by the two sets of winding sets 20 that are perpendicular to each other are perpendicular to each other, that is, between the two sets of winding sets 20 that are perpendicular to each other. The mutual inductance coefficient is basically zero. Correspondingly, electric energy cannot be transferred from the current winding group 20 to other winding groups 20 perpendicular to it by means of magnetic coupling. Therefore, the winding sets 20 that surround the support 10 and are perpendicular to each other are completely independent winding sets 20, and each set of winding sets 20 can transmit electrical signals with different phases.

For example, the transformer is provided with a first winding group 23 and a second winding group 24 surrounding the support 10, and the surrounding center line of the first winding group 23 is perpendicular to the surrounding center line of the second winding group 24. When the first winding group 23 is energized, the first winding group 23 forms an electromagnetic field, and the electric energy flowing in the first winding group 23 cannot be transferred to the second winding group 24 through magnetic coupling. When the first winding group 23 and the second winding group 24 are energized at the same time, the magnetic fields generated by the first winding group 23 and the second winding group 24 are independent of each other, and the maximum magnetic induction intensity of the transformer's magnetic field is the first winding group. When the wire group 23 and the second winding group 24 act independently, the magnetic induction intensity generated by the winding group 20 with the greater magnetic induction intensity is excited. The minimum value of the magnetic induction intensity of the magnetic field is the magnetic induction intensity generated by exciting the winding group 20 with the smaller magnetic induction intensity when the first winding group 23 and the second winding group 24 act independently.

As shown in FIG. 2, optionally, the transformer further includes a third winding group 25 surrounding the support 10, and the surrounding center line of the third winding group 25 is perpendicular to the surrounding center line of the first winding group 23, and at the same time, The surrounding center line of the third winding group 25 is perpendicular to the surrounding center line of the second winding group 24. In the transformer, any two sets of winding sets 20 are perpendicular to each other, and can combine or independently transmit electrical signals, which has high flexibility in use and basically does not affect its magnetic induction intensity.

A bracket 10 surrounds two or more winding groups 20, and the surrounding center lines between the winding groups 20 are perpendicular to each other, so that a transformer can simultaneously transmit electrical signals with different frequencies, amplitudes, and phases. The winding group 20 is vertically distributed on the support 10, so that a transformer can transmit two or three electrical signals with a phase difference of 90°, which improves the flexibility of the transformer, expands the application range, and reduces the transmission orthogonality. The volume of the signal control circuit board.

The transformer uses the principle of electromagnetic induction to change the input and output AC voltage. The winding group 20 surrounding the support 10 can adjust the output voltage or current signal through electromagnetic induction according to the connected voltage or current signal. Under the power-on condition, each group of the winding groups 20 can transform the input initial electrical signal through electromagnetic induction and output at least one corresponding output electrical signal.

As shown in Figures 2 and 3, in one embodiment, at least one set of the winding set 20 includes a primary coil 21 and at least one secondary coil 22 assembled on the support 10, and the primary coil 21 is connected to For the initial electrical signal, the at least one secondary coil 22 electromagnetically induces the primary coil 21 and outputs a corresponding output electrical signal. When the external power circuit inputs an AC current into the primary coil 21, an AC magnetic flux is generated in the stent 10, so that a voltage (or current) is induced in the secondary coil 22. In this embodiment, the primary coil 21 includes a terminal for connecting an external power supply circuit. One or more secondary coils 22 may be provided for connecting to a load circuit to realize one or more electrical signal output to match the requirements of different loads. According to the difference between the positive and negative poles, the phase of the electrical signal input by the primary coil 21 and the phase of the electrical signal output by the secondary coil 22 are the same or a phase difference of 180°. The winding group 20 can output one or more electrical signals, and can provide multiple loads with corresponding phase electrical energy, which is flexible in application and convenient to adjust.

Multiple sets of winding sets 20 surround the support 10 at the same time, and each two sets of winding sets 20 are perpendicular to each other. In each winding group 20, the phase of the electrical signal input by the primary coil 21 and the phase of the electrical signal output by the secondary coil 22 are the same or a phase difference of 180°. For example, when the phase of the electrical signal input from the primary coil 21 is the same as the electrical signal output from the secondary coil 22, the phases of the two are the same; the phase of the electrical signal input from the primary coil 21 is the same as the electrical signal output from the secondary coil 22. When the positive and negative signals are opposite, the phase difference between the two is 180°. In an embodiment, when the initial electrical signals of the two sets of winding sets 20 that are perpendicular to each other are orthogonal signals, the output electrical signals corresponding to the two sets of winding sets 20 are orthogonal. signal. The two sets of winding sets 20 that are perpendicular to each other surround the same support 10 to ensure that the overall size of the transformer is small. Each winding group 20 of the transformer can control the phase of the output signal according to the phase of the input electrical signal, so that one transformer can output output signals of different phases at the same time. That is, a transformer can output multiple output signals with quadrature signals, and the transformer can output one electrical signal as well as multiple electrical signals, which has a wide range of applications.

For example, the first winding group 23 includes a first primary coil and two first secondary coils, wherein the first primary coil is electrically connected to the first external power source, and the first secondary coil and the first primary coil are electrically connected to each other through electromagnetic induction. Form the induced voltage. The second winding set 24 includes a second primary coil and a second secondary coil, wherein the second primary coil is electrically connected to the second external power source, and the second secondary coil and the second primary coil form an induced voltage through electromagnetic induction .

Correspondingly, the working modes of the transformer include but are not limited to the following modes: a. Only the first winding group 23 works. One or two first secondary coils of the first winding group 23 are connected to the load circuit to provide power to the load circuit. b. Only the second winding group 24 works. The second secondary coil of the second winding group 24 is connected to the load circuit to provide power to the load circuit. c. The first winding group 23 and the second winding group 24 work at the same time, and one or two first secondary coils and second secondary coils are respectively connected to the same or different load circuits, so that the load circuits can receive different Phase electrical signal.

A transformer with multiple sets of mutually perpendicular winding sets 20, each set of winding sets 20 can be used independently or in combination, and the application scenarios are more flexible and the user experience is better. In an embodiment, the primary coil 21 and the secondary coil 22 include at least one of the following materials: enameled wire, flexible circuit board, and printed circuit printed on the PCB board. It is worth mentioning that the printed transformer technology is used to replace the enameled wire with a flexible circuit board or PCB to realize two or three sets of winding sets 20 that are perpendicular to each other to realize the function of a transformer, with a compact structure and flexible use. In occasions where space requirements are not so precise, the use of enameled wires can effectively reduce costs and enhance the versatility of the transformer.

In an embodiment, when the phase difference of the initial electrical signals of the two sets of winding sets 20 that are perpendicular to each other is 90 degrees, the phase difference of the electromagnetic fields generated by the two sets of winding sets 20 is 90 degrees. degree. When the phase difference of the voltages input to the two sets of mutually perpendicular winding sets 20 is 90°, the phase difference of the magnetic field excited by each set of winding sets 20 is also 90°. Correspondingly, the rotating magnetic field formed in the magnetic core or iron core of the transformer presents an elliptical track. Wherein, the maximum value of the magnetic induction intensity of the rotating magnetic field is the magnetic induction intensity generated by exciting the winding group 20 with a greater magnetic induction intensity when the two winding groups 20 act alone. The minimum value of the magnetic induction intensity of the rotating magnetic field is the magnetic induction intensity generated by the excitation of the winding group 20 with a smaller magnetic induction intensity when the two winding groups 20 act alone. Two sets of mutually perpendicular winding sets 20 act at the same time or only one set of winding sets 20 acts, the magnetic core or iron core has the same magnetic induction intensity, and the size and material adjustment requirements of the bracket 10 are small.

Each winding group 20 can operate independently, and can be used in combination with other winding groups 20. In an embodiment, the waveforms of the initial electrical signals transmitted by the winding set 20 are the same. For example, the waveforms transmitted by the two winding groups 20 include, but are not limited to: sine waves, square waves, triangle waves, and other waveforms. Among them, the waveforms transmitted by the two sets of winding groups 20 may have a corresponding phase difference, so that the transformer can output different electrical signals.

In another embodiment, the initial electrical signal transmitted by the winding set 20 has a difference. The winding groups 20 surround the support 10 perpendicularly to each other and do not interfere with each other. Accordingly, the amplitude, frequency, and initial phase transmitted by each group of winding groups 20 can be set arbitrarily. The waveforms transmitted by the two winding sets 20 can also be completely different. For example, the first winding group 23 transmits electrical signals of a sine wave waveform, and the second winding group 24 transmits electrical signals of a square wave waveform.

The transformer can transmit waveforms with phase differences or electrical signals with different waveforms at the same time, so that the transformer can provide corresponding electrical signals for different load circuits at the same time, with good flexibility in use and small installation space.
