    Abstract: The simultaneous transmission technology between wireless power and signals can realize information interaction between the primary and secondary sides. This paper, through employing the harmonic characteristics of the primary-side inverter, puts forward the simultaneous transmission technology between wireless power and signals based on the zero-series compensation. First, the compensation capacitor is not set in the primary-side system to obtain a non-sinusoidal current in the transmitting coil. Then, the fundamental component of the current is used to transmit power, and the harmonic content realizes signal transmission. The experimental results show that this technology can effectively reduce the volume and cost, and realize the fast and accurate signal transmission without affecting the power transmission.
    Key words: harmonic carrier; frequency deviation amplification; simultaneous transmission technology between wireless power and signals;zero-series compensation; non-sinusoidal current
