| 摘 要： | 磁耦合谐振式无线电能传输在传输特性、传输方向性、安全性等方面具有较大的优势,成为当前研究的热点。本文基于单片机设计了1台磁耦合谐振式无线电能传输装置,发射端采用单片机产生PWM波,作为高频逆变电路的驱动信号。单片机产生占空比可调的PWM波,并对占空比与输出电压的关系进行了实验分析。实验结果表明,当占空比为70%时,输出电压达到最大值,本系统可以点亮19cm处的LED。

| Abstract: | Magnetic coupling resonance has great advantages at transmission characteristics,transmission direction,and security,therefore,this way has caused the attention of domestic and foreign scholars.In this paper,a system about magnetic coupling resonance wireless power transmission was designed.The driving signal of the high frequency inverter is PWM which is generated by the MCU.And the duty cycle is adjustable.The relationship of the duty cycle and the output voltage is analyzed experimentally.The results show that when the duty cycle is 70%,the output voltage reaches the maximum,and the LED at 19cm is lighted up. |
