TECHNICAL FIELD

The present invention relates to wireless power transmission, and more particularly relates to a multi-transmitting multi-receiving magnetic-resonance wireless charging system for a medium-power electronic apparatus.

BACKGROUND

Traditional household appliances and electronic apparatus with built-in batteries are powered through a wired connection between a power line and a power socket. Electric utility lines and wires for supplying power to these electronic apparatus are ubiquitous. Such lines and wires not only occupy an activity space and limit the convenient use of the devices and apparatus, but also present safety hazards, some of which are hidden. Now, household appliances, consumer electronic products and mobile communication apparatus have been modernized with the evolution of electronic information and automation control technologies. Thus, with increased demand for a wireless-based portable device and a green energy grid system, research and application of a wireless energy transmission technology have rapidly become an area of focus in academic and industrial circles in China and throughout the world.

Currently, wireless charging technologies are mainly classified into three types. The first type is in compliance with the quality index (QI) standard mainly popularized by the Wireless Power Consortium (WPC). It is also referred to as a magnetic induction coupling technology. The second type uses a magnetic resonance coupling technology made popular by the Airfuel alliance. The third type uses an electromagnetic radiation-type wireless energy transmission technology. Compared with the magnetic induction technology, the magnetic resonance coupling technology has obvious advantages in charging distance, degrees of spatial freedom, one-to-many charging manner and power expansion. Meanwhile, the magnetic resonance coupling technology has a greater value when it comes to energy conversion efficiency, transmission power and electromagnetic safety than the electromagnetic radiation-type wireless energy transmission technology. The magnetic resonance coupling technology has found recent application in an intelligent wear device, a floor mopping robot, an automatic guided vehicle (AGV) and other apparatus. In these applications, the device includes a wireless charging function and so, the aforementioned concerns of safety and user experience enhancement are improved. Moreover, magnetic resonance coupling technology in the field of smart homes is changing the manner in which traditional household appliances, mobile communication devices and consumer electronics are used. Using a residential building structure as an exemplary platform, all the power lines in a domestic living area can be completely removed by using magnetic resonance wireless charging, concealed wiring and automatic control technologies. At the same time, apparatus is charged or powered continuously without wire connection, thereby improving a home's safety, residential convenience and comfort. A high-efficiency, environmentally friendly and energy-efficient living environment is achieved.

Wireless energy transmission modes and mechanisms mainly include a magnetic induction coupling mode, an electromagnetic radiation mode and a magnetic resonance coupling mode. The magnetic resonance coupling mode has advantages in safety and transmission efficiency compared with the electromagnetic radiation mode, and an advantage in transmission distance compared with the magnetic induction coupling mode. A single-transmitting single-receiving design solution adopted by a magnetic-resonance wireless charging design for a medium-power electronic apparatus which is disclosed currently has many disadvantages, including:

(1) A single receiving board bears large load power, in order to guarantee working stability, an electronic device has high electrical parameter indexes, such as a withstand voltage and a current value, resulting in a large package size. Therefore, it is difficult to minimize the whole design solution, namely to reduce the weight and size of the device while meeting wireless charging built-in requirements of small household appliances and consumer electronic products in the market.

(2) When energy of a magnetic field is received by the single receiving board, the magnetic field is fixedly distributed between receiving and transmitting components due to the use of the one-to-one solution and thus has a low horizontal degree of freedom.

(3) In a case of medium power output, the single receiving board bears large load power, and a power device generates a large amount of heat, which is not conducive to long-term stable operation.

The magnetic-resonance transmitting antenna is coupled with the magnetic-resonance receiving antenna in one-to-one correspondence. Each rectifier and filter module is connected to the receiving-end Bluetooth-communication and control module.

In an embodiment of the present invention, the output power of the multi-transmitting multi-receiving magnetic-resonance wireless charging system is set to be 30 W. The 6.78 mHz excitation signal is amplified by the radio-frequency power amplifier source and is added to the magnetic-resonance transmitting antenna, the energy is then transmitted to the magnetic-resonance receiving antenna in a magnetic resonance coupling manner. Electromagnetic energy received by the magnetic-resonance receiving antenna is rectified and filtered to enter the two-stage regulator circuit for voltage regulation, and then to output. The magnetic-resonance transmitting antennas correspond to the magnetic-resonance receiving antennas one by one. Each magnetic-resonance receiving antenna uniformly receives the electromagnetic energy of the corresponding magnetic-resonance transmitting antenna. The electromagnetic energy is output from a resonance coil of the magnetic-resonance receiving antenna and is then input into the corresponding rectifier and filter module. The electromagnetic energy is input into a rectifier module through a port of the matching network and is converted into a direct-current electric energy after passing through a bridge rectifier circuit. After the direct-current electric energy passes through a filter circuit, a direct-current electric energy of 23V is output through the regulator chip and a regulator peripheral circuit. After the direct-current electric energy of 23 V passes through the regulator chip controlled by the protocol chip, the voltage of the direct-current electric energy is stabilized at 20V Finally, the direct-current electric energy is synthesized into one-channel direct-current electric energy by means of power synthesis to be output to consumer electronic products, communication apparatuses and notebooks for use.
