Abstract:

In order to optimize the transmission power and efficiency of the rail-type contactless power transfer（CPT） system,a new method is proposed based on the impendence character.Then,the relationships between the transmission power and such parameters as the equivalent reluctance of the magnetic core,the operation frequency of the system as well as the number of primary and the secondary coils are analyzed.Moreover,an optimized design procedure of the rail-type CPT system is presented according to the practical requirement of power transmission,which implements the optimal control of power transmission by optimizing the input voltage and the number of the primary and the secondary coils,and increases the system efficiency as high as possible.Experimental results show that the proposed method is theoretically valid and practically feasible.

Key words: rail-type CPT system, transmission power, efficiency, optimization
