Simultaneous wireless power and multi-channel data transmission based on OFDM

Aiming to meet the demand for multi-channel data communication between the power transmitter and receiver in a wireless power transfer system, a simultaneous wireless power and multi-channel data transmission method based on orthogonal frequency division multiplexing (OFDM) is proposed. In this method, a dual-LC resonant network is employed in the data transmitting circuits, which can achieve two independent data transmitting with only one data transmitting transformer. By making the power carrier and data carriers orthogonal to each other, the multi-channel data can be demodulated based on OFDM demodulation principle without requiring a filtering circuit and sampling resistance in the data receiving circuits. The power transmission adopts the bilateral LCC topological structure to achieve a load-independent constant current output. The data transmission characteristics are optimized by analyzing the system parameters impact on the data transmission gain. A 40 W experimental platform is built and a 4 × 85 kbps data transmission rate is achieved. Experimental results show that four-channel data in two forward and two backward channels can be transmitted accurately without interference from the power and other data carriers according to the OFDM principle. Moreover, the proposed system exhibits a high data bandwidth utilization.

Abstract

Aiming to meet the demand for multi-channel data communication between the power transmitter and receiver in a wireless power transfer system, a simultaneous wireless power and multi-channel data transmission method based on orthogonal frequency division multiplexing (OFDM) is proposed. In this method, a dual-LC resonant network is employed in the data transmitting circuits, which can achieve two independent data transmitting with only one data transmitting transformer. By making the power carrier and data carriers orthogonal to each other, the multi-channel data can be demodulated based on OFDM demodulation principle without requiring a filtering circuit and sampling resistance in the data receiving circuits. The power transmission adopts the bilateral LCC topological structure to achieve a load-independent constant current output. The data transmission characteristics are optimized by analyzing the system parameters impact on the data transmission gain. A 40 W experimental platform is built and a 4 × 85 kbps data transmission rate is achieved. Experimental results show that four-channel data in two forward and two backward channels can be transmitted accurately without interference from the power and other data carriers according to the OFDM principle. Moreover, the proposed system exhibits a high data bandwidth utilization.
