摘要
针对旋转超声振动加工中接触式超声频、大功率电能传输存在的问题,提出基于电磁耦合感应的非接触电能传输方法。理论分析了非接触松耦合变压器的参数设计,建立了以压电换能器和松耦合变压器为总负载的原边电端阻抗匹配模型。实验研究了电源频率、磁芯间距对电能传输效率的影响,测试了系统工作过程中磁芯的温升变化,结果表明所设计的非接触电能传输系统能够满足旋转超声振动加工要求。
In order to solve the ultrasonic frequency and high power transmission problems in rotary ultrasonic vibration machi- ning, the Contactless Power Transmission （CPT） method based on electromagnetic inductive coupling was proposed. The design parameters of contactless loosely coupled transformer were calculated by theoretical analysis. The original boundary imPedance matching model with the total load of piezoelectric transducer and contactless loosely coupled transformer was established. The re- lationship between power frequency, magnetic core spacing and power transmission efficiency was studied by experimental analysis and the trend of temperature variation of magnetic core was tested. The results show that the contactless power transmission system can meet the requirements of rotary ultrasonic vibration machining.
