[Abstract]:Wireless Power transfer (WPT) has the advantages of security, convenience, compatibility and so on, compared with the traditional power supply, so it has great research value and broad application prospect. With the continuous development of technology, radio energy transmission methods are becoming more and more abundant, including electromagnetic induction (IPT), electromagnetic resonance (MR-WPT), electromagnetic radiation (MPT) and many other radio energy transmission methods have been developed and applied. In recent years, radio energy transmission technology has made great contributions in biomedical, electric vehicles, household appliances and many other fields. This paper focuses on the application of electromagnetic induction radio energy transmission technology in medium power household appliances, focusing on the design of dual load radio energy transfer (DIPT) system and its transmission characteristics. In this paper, the equivalent circuit is established by using mutual inductance model. By theoretical derivation, the related parameters of DIPT system transmission characteristics under different resonant compensation structures are obtained, including reflecting impedance, power transmission capacity and transmission efficiency. Critical condition of frequency bifurcation. By using the software of OrCAD and MATLAB, the influence of various parameters on the transmission characteristics of the system is discussed, including coupling coefficient, double load resistance, working frequency, etc. At the same time, the steady state change of IPT system from single load mode to double load mode is analyzed. Secondly, the design of DIPT system is completed, including hardware circuit design (inverter circuit, absorption circuit, etc.), magnetic coupling mechanism design: through simulation analysis, the appropriate compensation structure is selected. The coil structure is optimized by Ansoft Maxwell. Finally, an experimental device with working frequency of 60 kHz and output power of about 700W with the highest efficiency of 92% is obtained. Combined with the simulation results, the transmission characteristics of DIPT system are verified by a series of characteristic experiments, including variable load characteristic experiment, lateral shift characteristic experiment, single and double load contrast experiment. The simulation results are consistent with the experimental results in terms of transmission power and efficiency with load, coupling coefficient and other parameters. In addition, the load characteristics of IPT system motor are studied by MATLAB simulation and experiment method, and the application of radio energy transmission technology in home appliances is extended. Finally, the power coordinated control mode of DIPT system is discussed, and the feasibility of variable load, frequency conversion and capacitor regulation is analyzed by combining OrCAD simulation with experimental verification. The results show that the capacitive regulation method has a certain function of regulating the dual load power coordination in theory.
