感应电能传输（IPT）是一种新型家用电器供电技术，可消除火花和电线的影响。此外，智能家居是一种流行的智能系统，用于连接家庭中的设施。为了将IPT技术与智能家居系统的优势完美结合，对于IPT系统来说，控制信号的传输与电源的传输同样重要。本文提出一种将电源和控制信号从供电端同步传输到接收端的方法，实现电视、空调、空气净化器等家用电器的无线供电和智能控制。该方法将逆变器输出电压的基波和谐波分量分别作为功率载波和信号载波。一是为家用电器供电，二是向家用电器传输控制信号。在此方法的基础上，充分利用了谐波能量低、频率高的特点，既实现了稳定的电力传输，又实现了高速的信号传输。通过kW级实验平台验证了该方法的有效性。
Inductive power transfer (IPT) is a new power supply technology for household appliances to eliminate the effects of sparks and wires. Besides, the smart home is a popular intelligent system to connect the facilities in the home. To combine the advantages of IPT technology and smart home system perfectly, the transmission of the control signal is as important as the transmission of power for IPT system. This work proposes a method that makes the power and control signal transmission synchronously from the supply side to receiving end to achieve the wireless power supply and the intelligent control for household appliances such as televisions, air conditioners, air purifiers etc. In the proposed method, the fundamental and harmonic components of the inverter output voltage are used as the power carrier and the signal carrier, respectively. One is to supply power to household appliances and the other is to transmit a control signal to them. On the basis of this method, the features of harmonics such as low energy and high frequency are well used, which enable both stable power transmission and high‐speed signal transmission. The effectiveness of the proposed method is verified by an experimental platform of kW level.
