Abstract

A novel multi-load Parity-Time (PT) wireless power transmission (WPT) system with active directional energy transmission is designed. Firstly, we utilize a variable capacitor array to achieve selective mutual coupling between a single transmitting coil and multiple receiving coils. Then, under the action of the control circuit, the system can prioritize charging low-capacity batteries and automatically switch charging modes after the load is charged. Furthermore, different from the existing multi-load PT-WPT system, the DC-DC converter is added to the receiving device in this design. The DC-DC converter ensures that the system can provide constant current (CC) or constant voltage (CV) charging modes depending on the load requirements. Through the above design, we have constructed a new multi-stage charging mode in the multi-load PT-WPT system. The experimental results show that the system can achieve active directional energy transfer and provide different charging modes according to the needs of the loads. Moreover, the system also exhibits features such as a wide coupling and actively switching charging modes. The use of a multi-load PT-WPT system with active directional energy transmission can provide efficient charging strategies for wireless sensor networks with multiple loads.

期刊介绍： The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
