| description | The invention provides a coil current demodulation method and circuit based on a wireless charging transmitting terminal, and the method comprises the steps: sampling a transmitting terminal coil current signal, carrying out the signal processing of the sampled transmitting terminal coil current signal, and completing the demodulation of the coil current. The method has the beneficial effects that by directly sampling the transmitting end coil circuit signal, the problem that a traditional ASK demodulation mode has an error in signal sampling can be solved.
本发明提供一种基于无线充电发射端的线圈电流解调方法及电路，所述线圈电流解调方法为：采样发射端线圈电流信号，并对采样的发射端线圈电流信号进行信号处理后完成线圈电流解调。本发明的有益效果是：本发明通过直接采样发射端线圈电路信号，能够解决传统的ASK解调方式在信号采样上存在误差的问题。 |
