Magnetic coupling radio energy transmission technology has no technical principle of bottlenecks, the key is how to do a good job. The current industrialization difficulties mainly focus on how to miniaturize the transmitter and receiver to meet the market demand.

According to the latest research, magnetic coupled resonant radio power transmission (MCR-WPT) is becoming a hot research field in the field of radio power transmission because of its efficient energy transmission characteristics. The technology can be transmitted over a distance of several meters, power range from tens of Watts to several kilowatts, transmission efficiency of 40% to 90% , showing a wide range of potential applications.

However, despite the continuous progress of technology, there are still some challenges in practical application, such as low conversion efficiency of inverter source and overall transmission efficiency caused by improper design of coupling coil parameters, as well as high-frequency electromagnetic field brings electromagnetic pollution. Therefore, how to optimize these technical details, enhance the market competitiveness of products, is still the current industry's top priority.

Zhonghui Chuangzhi (Shenzhen) Wireless Power Supply Technology Co. , Ltd. has been committed to technical innovation and product development to meet the market demand for small, efficient wireless charging solutions. Here are some of our research and technological innovations in the miniaturization design of the transmitter and receiver:

1.Application of high performance materials

we use high permeability materials as magnetic core of the coil, which not only reduces the coil size, but also increases the magnetic field strength, thus improving the energy transmission efficiency.

2.Optimization of compensation network

By adjusting the compensation network parameters accurately, we achieve the optimal working state of the system under different loads, and further improve the transmission characteristics and efficiency of the system.

3. Exploration of metamaterial technology

In our research, we have explored the negative refractive index properties of metamaterials, which can be used to concentrate divergent magnetic fields and improve the coupling and transmission efficiency of the system.

4. Improvement of control strategy

We adopt the control strategy based on energy balance to improve the dynamic performance and stability of the system, and ensure the high efficiency and stable output under various working conditions.

5. Multi-objective optimization of system parameters

By using the multi-objective parameter optimization method, the system efficiency, capacitance voltage and inductance current are considered, and the optimal system configuration is found.

6.Integrated design

We design the integrated circuit components of the transmitter and receiver to reduce the space consumption and realize the miniaturization. By using high-density integration technology and miniaturized components, we achieved a compact design of the system without sacrificing performance.

7.Optimization design of high frequency inverter

We have optimised the design of the high-frequency inverter by using a miniaturised, high-efficiency inverter that reduces the size of the system while increasing energy efficiency.
