摘要
针对非接触式电能传输存在的传输效率不高的问题,分析了影响非接触式电能传输系统传输功率和传输效率的因素,利用互感理论搭建了基于MATLAB/Simulink的仿真系统模型。在不同的开关频率和互感系数下,研究了开关频率、互感系数与系统传输功率和传输效率之间的关系。仿真结果表明,系统在开关频率为60 k Hz时,传输效率达到峰值。
Aiming at the lower transmission efficiency in non-contact power transmission,this paper analyzed the factors which affect the transmission power and transmission efficiency of the non-contact power transmission system.Meanwhile,a system model which is based on MATLAB / Simulink simulation platform according to mutual theory was built to study the relationship between the switching frequency,the mutual inductance and transmission power,transmission efficiency at different values of mutual inductance and the switching frequency. The simulation results show that the transmission efficiency of the system reaches the peak value when the switching frequency is 60 k Hz.
