Abstract

Contactless power transmission system can supply power in non-contact way for many electronic equipments, it has become a hot topic in recent research. Take topological structure of serial-parallel CPT system for example, the optimal values of the compensation capacitors which can solve the poor coupling problem of the separable transformer are determined. A frequency tracking control system based on single chip microcomputer was designed, which can overcome the problem of system resonant frequency changed in the conditions of load switch and different transmission distances to improve the transmission power. Simulation and experiment proved the correctness of theoretical analysis.
