Static Loss

Aiming at the problems existing in the current radio energy transmission system, we propose a wireless power transmission (WPT) system with the parallel–parallel (PP)-compensated structure. The transmitter of the transmission system adopts a separate topological structure to suppress the current shock and noise. In order to improve the efficiency of the WPT, reduce the static loss, and reduce the current oscillation loss on the power side, the input current ripple can be improved by two parallel phase-shifting methods. In this paper, two topological theories are analyzed, and the simulation and experiment results verify the correctness of these theories under both static and on-load conditions. After the final two-way phase-shift, 61.99% of the ripple is reduced. It provides a new approach for the design of WPT systems with PP structure.

Novel Method

In order to solve the problem that electromagnetic induction widely used now is just suited to short distance transmission, and study on the transmission characteristics of wireless power transmission system based on magnetic resonant coupling, a novel method that the two separate-coupling coils achieve wireless power and information synchronous transmission is proposed. The basic theory of wireless power transmission and information system is introduced. The condition that resonant frequency splitting phenomenon is produced of a contact-less power transmission system has been deduced, and it depend on the length of distance between the two coils. The principle prototype of transmission system is designed, and transmission characteristics of the system are analyzed by simulation and experiment. Based on circuit formulation, maximum efficiency is found to exist. The results show that the method of wireless power and information synchronous transmission system is in agreement with theoretical analysis.
