基于电容调制的无线电能传输系统信号电能同步传输

The capacitor modulation of the signal is achieved by modifying the compensation capacitance. Through artificial influence on operation condition of the resonator, the voltage across the coil can be effectively controlled. Through a series of signal processing links, such as step-down dividing voltage, demodulating, filtering, comparing and so on, the transmitting signal is reproduced. The simulative and experimental results demonstrate that the proposed scheme is effective, where the signal can be sent and extracted correctly, and the impact on power transmission is relatively small. In these regards, the synchronous transmission of signal and power in WPT (Wireless Power Transmission) system is realized.
