- Abstract
With the diversification of electronic devices and the complexity of application scenarios, how to provide the required power to various electronic devices has become an urgent problem in the field of wireless power transfer (WPT). The multiple-input multiple-output wireless power transfer (MIMO-WPT) system is a viable solution to this problem by providing power to multiple receiving loads simultaneously. Aiming at the different power requirements of multiple receiving loads in multiple-input/multiple-output (MIMO) radio energy transmission system, this paper proposes a power allocation method with the optimization goal of minimizing power allocation error and maximizing efficiency, and verifies the feasibility of the method through simulation experiments. The results show that the system can allocate power according to the different power requirements of each load, the maximum allocation error is not more than 2.75%, and the maximum transfer efficiency reaches 74.4%. The optimal power allocation method proposed in this paper provides an effective solution to the problem of different power requirements of multiple receiving loads in MIMO-MCRWPT systems, which can achieve transfer efficiency optimization with minimum power allocation error.
