Abstract

The invention discloses a design method based on topology structures for a condition criterion wireless energy transmission system. The design method comprises the following steps of: firstly, analyzing the different topology structures from an angle of an equivalent circuit so as to acquire an expression of the optimal transmission efficiency of the transmission system in the different topology structures; secondly, defining a condition criterion related to load resistance, transmission distance, resonance frequency and coil sizes; and finally, calculating the condition criterion according to specific parameters when the wireless energy transmission system actually applied is designed, and selecting suitable topology structures for the wireless energy transmission system according to the condition criterion so as to acquire the optimal transmission efficiency. According to the design method, the topology structures for the wireless energy transmission system can be fast, conveniently and effectively designed according to the value of the condition criterion, so that the optimal transmission efficiency of the system is acquired.
