For example, fig. 1 is a block diagram of a transformer according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a transformer 10, including: a power supply circuit 100, wherein the power supply circuit 100 includes a power supply antenna 110, and the power supply circuit 100 is configured to transmit power through the power supply antenna 110; and a power receiving circuit 200, wherein the power receiving circuit 200 includes a power receiving antenna 210, and the power receiving circuit 200 is configured to receive the power transmitted by the power supply antenna 110 through the power receiving antenna 210.
For example, the embodiment of the present invention provides a transformer 10 that transmits power through the power supply antenna 110 and the power receiving antenna 210, without a magnetic core, thereby reducing the volume and weight of the transformer and reducing the magnetic core loss.
For example, fig. 2 is a schematic diagram of a transformer according to an embodiment of the present invention. As shown in fig. 2, in the transformer 10 according to the embodiment of the present invention, the feeding antenna 110 is disposed separately from the receiving antenna 210. For example, the feeding antenna 110 and the receiving antenna 210 are disposed on different printed circuit boards.
For example, the power supply circuit 100 further includes a power supply circuit 120 and a power supply printed circuit board 130, the power supply circuit 120 being disposed on the power supply printed circuit board 130; the electricity receiving circuit 200 further includes an electricity receiving circuit 220 and an electricity receiving printed circuit board 230, and the electricity receiving circuit 220 is disposed on the electricity receiving printed circuit board 230.
For example, the feeding antenna 110 is electrically connected to the feeding loop 120, and converts an energy signal (e.g., a high-frequency oscillating current, a guided wave, or an energy carrier in other forms) provided by the feeding loop 120 into an electromagnetic wave for transmission. The receiving antenna 210 is electrically connected to the receiving loop 210, and the receiving antenna 210 converts the received electromagnetic wave into a corresponding energy signal (e.g., a high-frequency oscillating current, a guided wave, or an energy carrier in other forms) and transmits the energy signal to the receiving loop 210. The power supply circuit 210 may convert the energy signal into electrical energy for storage or utilization. Therefore, the transmission of power between the power supply terminal and the power reception terminal can be achieved by the power supply antenna 110, the power supply circuit 120, the power reception circuit 210, and the power reception antenna 210.
For example, in the transformer 10 according to the embodiment of the present invention, the feeding antenna 110 and the receiving antenna 210 are both helical antennas. For example, the feeding antenna 110 and the receiving antenna 210 are both cylindrical helical antennas. For example, the cylindrical helical feed antenna 110 is disposed coaxially with the cylindrical helical receive antenna 210. For example, the coaxial arrangement of the cylindrical helical feed antenna 110 and the cylindrical helical collector antenna 210 can improve the efficiency of power transmission between the cylindrical helical feed antenna 110 and the cylindrical helical collector antenna 210. It should be noted that the feeding antenna 110 and the receiving antenna 210 provided in the embodiment of the present invention include but are not limited to a helical antenna or a cylindrical helical antenna, and the shapes of the feeding antenna 110 and the receiving antenna 210 may be selected according to actual needs.
For example, if the current flowing through feed antenna 110 is I, the number of coil turns of feed antenna 110 is n, and the coil radius of feed antenna 100 is r, the magnetic field strength at a position having a transmission distance x (for example, a position having a distance x in the axial direction of feed antenna 100) is H, which satisfies the following equation:
wherein,
for example, the receiving antenna 210 may be located at a transmission distance x. For example, the number and radius of the coil turns of the power feeding antenna 110, the number and radius of the coil turns of the power receiving antenna 210, and the distance between the power feeding antenna 110 and the power receiving antenna 210 may be selected according to the need for actual power transmission.
For example, in the transformer 10 provided in the embodiment of the present invention, the power supply circuit 100 includes a power supply ground terminal, and the power receiving circuit 200 includes a power receiving ground terminal, and the power supply ground terminal is electrically connected to the power receiving ground terminal. For example, the power supply circuit 120 includes a power supply ground, and the power receiving circuit 220 includes a power receiving ground, which is electrically connected to the power supply ground. The stability of the transformer 10 may be improved by electrically connecting the power supply ground terminal and the receiving ground terminal.
For example, fig. 3 is a second schematic diagram of a transformer according to an embodiment of the present invention. As shown in fig. 3, in the transformer 10 provided in the embodiment of the present invention, the power supply circuit 100 includes the power supply antenna 110 and the power supply loop 120, and the power receiving circuit 200 includes the power receiving antenna 210 and the power receiving loop 220. The feeding circuit 120, the feeding antenna 110, the receiving antenna 210, and the receiving circuit 220 are disposed on the same printed circuit board 140.
For example, the power supply circuit 120, the power supply antenna 110, the power receiving antenna 210 and the power receiving circuit 220 are disposed on the same printed circuit board 140, so that the size of the transformer 10 can be reduced, the space can be saved, and the efficiency of the transformer 10 can be improved, and at the same time, since only one printed circuit board 140 needs to be designed, the design of the transformer is easier.
For example, as shown in fig. 3, the power supply circuit 120 includes a power supply ground terminal 121, the power receiving circuit 220 includes a power receiving ground terminal 221, and the power supply ground terminal 121 is electrically connected to the power receiving ground terminal 221. For example, the electrical connection of the supply ground to the reception ground may improve insulation and stability of the transformer 10.
For example, fig. 4A is a third schematic diagram of a transformer according to an embodiment of the present invention, fig. 4B is a schematic top view of the transformer shown in fig. 4A, and fig. 4C is a schematic bottom view of the transformer shown in fig. 4A. As shown in fig. 4A, 4B and 4C, in the transformer 10 provided in the embodiment of the present invention, the printed circuit board 140 includes a first side 141 and a second side 142 opposite to each other, the power supply antenna 120 is disposed on the first side 141 of the printed circuit board 140, and the power receiving antenna 210 is disposed on the second side 142 of the printed circuit board 140. For example, the power supply antenna 110 is disposed on the surface of the first side 141, and the power reception antenna 210 is disposed on the surface of the second side 142.
For example, the power supply antenna 110 and the power receiving antenna 210 are respectively disposed on the first side 141 and the second side 142 of the printed circuit board, so that the distance between the power supply antenna 110 and the power receiving antenna 210 can be reduced, the space can be saved, the size of the transformer can be reduced, and the transformer can be designed more easily and more efficiently.
For example, in the transformer 10 according to the embodiment of the present invention, the feeding antenna 110 and the receiving antenna 210 are both helical antennas. For example, the feeding antenna 110 and the receiving antenna 210 are both cylindrical helical antennas. For example, in the transformer 10 according to the embodiment of the present invention, the cylindrical spiral feed antenna 110 and the cylindrical spiral receive antenna 210 are coaxially disposed, as shown in fig. 4A, that is, the axis 150 of the cylindrical spiral feed antenna 110 coincides with the axis of the cylindrical spiral receive antenna 210. For example, the coaxial arrangement of the cylindrical helical feed antenna 110 and the cylindrical helical collector antenna 210 can improve the efficiency of power transmission between the cylindrical helical feed antenna 110 and the cylindrical helical collector antenna 210. It should be noted that the shaft 150 is a geometric attribute of the cylindrical antenna, is not a component of the cylindrical helical power feeding antenna 110 or the cylindrical helical power receiving antenna 210, and is only used to illustrate a positional relationship between the cylindrical helical power feeding antenna 110 and the cylindrical helical power receiving antenna 210. In some embodiments, the axis of the cylindrical helical feed antenna 110 and the axis of the cylindrical helical receive antenna 210 may be disposed parallel to each other, and may not coincide.
For example, in the transformer 10 according to the embodiment of the present invention, the axis 150 of the cylindrical spiral feeding antenna 110 and the axis of the cylindrical spiral receiving antenna 210 are perpendicular to the surface of the first side 141 or the surface of the second side 142, that is, the cylindrical spiral feeding antenna 110 and the cylindrical spiral receiving antenna 210 are perpendicular to the printed circuit board. This arrangement can further reduce the volume of the transformer 10.
For example, wireless power supply methods are classified into a non-radiation type and a radiation type, wherein the radiation type wireless power supply includes electromagnetic induction type wireless power supply and resonance type wireless power supply, and the radiation type wireless power supply includes radio wave reception type wireless power supply. Resonant wireless power supplies, for example, can transmit less than 10 kilowatts of power in 10 meters, have 30% to 60% efficiency, and have a large degree of positional freedom. For example, the embodiment of the present invention provides a transformer 10 that is a resonant wireless power supply transformer.
For example, the embodiment of the present invention provides the transformer 10 with an operating frequency of 10kHz to 30 MHz.
For example, fig. 5 is a second block diagram of a transformer according to an embodiment of the present invention. As shown in fig. 5, in the transformer 10 provided in the embodiment of the present invention, the power supply circuit 120 includes a power supply resonance circuit 121 and a high frequency resonance modulation circuit 122; the power reception circuit 220 includes a power reception resonance circuit 221 and an ac-dc converter 222.
For example, the feeding resonant circuit 121 and the high frequency resonance modulation circuit 122 provide the feeding antenna 110 with an energy signal for transmission, the feeding antenna 110 converts the energy signal into an electromagnetic wave and transmits the electromagnetic wave to the receiving antenna 210, and the receiving antenna 210 receives the electromagnetic wave and converts the electromagnetic wave into a corresponding energy signal. The resonance circuit 221 converts the received energy signal into an ac signal, and the ac-dc converter 222 converts the ac signal into a dc signal. The direct current signal is processed to be used for supplying power to a load.
For example, in the transformer 10 provided in the embodiment of the present invention, the power supply circuit 120 further includes a power supply 123, a gate driver 124, a control circuit 125, a crystal oscillator 126, and a power supply communication circuit 127; the receive circuit 220 also includes a dc transformer 223, a voltage regulator 224, battery monitoring circuitry 225, a battery 226, and receive communication circuitry 227 that may communicate with the supply communication circuitry 127.
For example, the frequency of the crystal oscillator 126 is 27.12 MHz.
For example, the gate driver 124 includes a gallium nitride (GaN) or Metal Oxide Semiconductor (MOS) gate driver.
For example, in the transformer 10 provided in the embodiment of the present invention, the power supply communication circuit 127 and the power reception communication circuit 227 are both wireless communication circuits. For example, the power supply communication circuit 127 and the radio communication circuit 227 are each a bluetooth (bluetooth) communication circuit or a wireless personal area network (zigbee) communication circuit. Of course, the power communication circuit 127 and the power receiving communication circuit 227 may also be wired communication (e.g., electrical or optical cable communication).
For example, in the power supply circuit 100, the control circuit 125 converts the signal generated by the crystal oscillator 126 into the frequency required by the high-frequency resonance tone-varying circuit 122 (i.e., the frequency required for the power supply antenna 110 to radiate, for example, 13.56MHz) through the gate driver 124.
The power supply communication circuit 127 may receive the control signal transmitted by the power receiving communication circuit 227. The control signal may include a start power supply signal, a stop power supply signal, or other control signals. For example, when the power supply communication circuit 127 receives a power supply stop signal transmitted by the power receiving communication circuit 227, the power supply communication circuit 127 transmits the power supply stop signal to the control circuit 125, so that the control circuit 125 transmits a power supply stop signal to the power supply 123 and the power supply 123 (e.g., a dc power supply) stops supplying power. When the power supply communication circuit 127 receives the power supply signal sent by the power receiving communication circuit 227, the power supply communication circuit 127 transmits the power supply signal to the control circuit 125, so that the control circuit 125 sends the power supply signal to the power supply 123 and the power supply 123 supplies power. The high-frequency resonance tone varying circuit 122 converts the power supplied from the power supply 123 into an electric signal for transmission, and the electric signal is resonated by the power supply resonance circuit 121 and then transmitted by the power supply antenna 110. Of course, the receiving communication circuit 227 may also receive a signal transmitted by the power supply communication circuit 127.
For example, in the power reception circuit 200, the power reception antenna 210 receives an electromagnetic wave emitted from the power supply antenna 110 and converts the electromagnetic wave into an energy signal (for example, a high-frequency current signal), the power reception resonance circuit 221 converts the energy signal into an alternating current signal, and the alternating current/direct current converter 222 converts the alternating current signal into a direct current signal. The dc transformer 223 may convert the voltage of the dc signal to a suitable operating voltage. The dc transformer 223 may transmit the transformed dc signal to the voltage stabilizer 224, and the dc signal may be transmitted to the load 300 of the transformer 10 after being stabilized by the voltage stabilizer 224. The dc transformer 223 may also transmit the transformed dc signal to the battery 226 for charging (e.g., via a battery management chip), and also provide power to the battery monitoring circuit 225, wherein the battery monitoring circuit 225 is configured to monitor a state of the battery 226 (e.g., a state of charge of the battery 226). The dc transformer 223 may also transmit the transformed dc signal to the transceiver circuit 227 to supply power to the transceiver circuit 227. The receive electrical communication circuit 227 may receive battery status information sent by the battery monitoring circuit 225 and transmit the information to the power supply communication circuit 127.
For example, battery 226 may also supply power to load 300 via the output of voltage regulator 224. For example, when the charge level of the battery 226 drops below a charge level threshold (e.g., 30%), the battery monitoring circuit 225 sends a signal to the receiver communication circuit 227 that the battery is low, and the receiver communication circuit 227 sends this signal to the supply communication circuit 127 via wireless communication (e.g., bluetooth or zigbee). The power supply communication circuit 127 transmits the received signal to the control circuit 125, causing the control circuit 125 to control the power supply 123 to start supplying power (i.e., the power supply circuit 100 starts supplying power to the load 300 while charging the battery 226). When the charging of the battery 226 is completed, the power supply circuit 100 stops supplying power, and the load 300 is powered by the battery 226. For example, the power supply circuit 100 may also be powered continuously, and the battery 226 may be used only as a backup.
For example, the control circuit 125 may be implemented by a programmable circuit such as a DSP, FPGA, PLC, or the like.
For example, the battery monitoring circuit 225 may be implemented by a single chip microcomputer.
