Abstract
- The data communication always needs to be implemented in application of the Wireless Power Transfer (WPT) technology. However, there are also some problems need to be dealt with in practical applications. For example, the interference between power transfer and communication is serious, when the power and data are transmitted through the same coupling coil. A simple design is presented to implement bidirectional communication through the power transmission channel in this paper. The main idea is that the high-frequency signal can be sent via a single antenna. The power is transferred in the frequency range of 20 KHz to 100 KHz, the data is transferred by employing carrier at around 10MHz. The interference between the two function is analyzed. In order to demonstrate the effectiveness of the proposal, a hardware experiment prototype platform is built up in the project. In the experiment, the transmission gap distance is 10mm, the power transfer is reached 30W, and the data transmission rate is capable of up to 80 Kbps.
