|
摘要
为了提高超声磨削加工系统中非接触电能传输系统电能传输的效率,建立了电信号非接触传输装置感应模型,推导了超声系统电信号非接触传输装置传输效率和总输入阻抗的表达式,从理论上分析了分布电容和线圈自感对电能传输效率和输出阻抗的影响。实验结果表明通过改变线圈绕组的结构、调整瓷罐间隙可以提高传输效率,获得最大有效功率。
Aiming at improving the efficiency in the non-contact power transmission system of ultrasonic grinding system,an induction model of electrical signal non-contact power transmission device was established. The equation of transmission efficiency and total input impedance of the non-contact transmission power device of the electrical signals in ultrasonic system were derived. The influence of distributed capacitance and coil self-inductance on power transmission efficiency and output impedance were theoretically analyzed. The experimental results show that the transmission efficiency can be improved to obtain the maximum effective power by changing the structure of the coil winding and adjusting the gap of the porcelain tank.
