| 摘 要： | 介绍了无接触电能传输系统的组成及工作原理,以高频变换器为主,对系统进行了分析。为提高逆变器的传输效率,达到降低高频开关损耗的目的,以Matlab/Simulink工具箱为基础建立了SPWM逆变器的仿真模型,并进行仿真。仿真结果显示,当PWM脉冲发生器的输出电压频率为400 Hz、载波频率为1.2 kHz时的传输效率最高。

| Abstract: | This paper introduced the composition and operating principle of the contactless power transmission system.The system was analyzed based on the high-frequency converter.To improve the efficiency of the inverter and reduce the switchloss,the SPWM inverter simulation model was built based on the Matlab/Simulink toolbox and the waveform was analyzed.The simulation results showed the transmission efficiency is highest when the PWM pulse generator frequency of output voltage is 400 Hz and carrier frequency is 1.2 kHz. |
