[Abstract]:Different from the traditional contact power transmission technology, the non-contact power transmission technology utilizes the principle of electromagnetic induction of loosely coupled transformer and uses air as the transmission medium to realize wireless power transmission. It can be widely used in various flammable, explosive and underwater power supply environments, and can effectively improve the security and reliability of power transmission. This paper first introduces the development of contactless power transmission technology at home and abroad, and analyzes the structure and working principle of the components of contactless power transmission device, especially discusses loosely coupled transformer, high frequency inverter, RCC voltage stabilizer. The related technologies such as capacitive compensation and over-current overvoltage protection lay a theoretical foundation for the subsequent design of low-power contactless power transmission devices. Secondly, combined with the requirement of low power non-contact power transmission, the loose coupling transformer is designed. The optimization design of the loose coupling transformer core, the winding analysis and the calculation of the relevant parameters of the loosely coupled transformer are carried out. Thirdly, the main circuit and control circuit of the low power contactless power transmission device are designed. Aiming at improving the transmission efficiency of the system, the suitable output voltage frequency is selected, and the voltage type bridge high frequency inverter circuit is designed. At the same time, the SP capacitor compensation circuit is introduced on both sides of the loosely coupled transformer, which reduces the reactive power loss of the system and improves the coupling coefficient. Considering the fluctuation factor of the output voltage, the secondary voltage feedback circuit is used to improve the stability of the output voltage of the system. Finally, the power and efficiency of the low power contactless power transmission device are tested under load and no load. The test results show that the low power contactless power transmission device has the advantages of stable output voltage and high transmission efficiency, and meets the design requirements.
