Abstract

In order to maximize the power transmission capability of the magnetic coupling resonant wireless power transmission system, and to improve the efficiency of the whole system, a compensation circuit design method which based on LCC three order network is proposed. The proposed method, which is not affected by the receiver reflected impedance, can keep the current in the transmitter coil constant, make the design procedure of the inductive contactless power transmission (ICPT) system transmitter and receiver decoupled. In the meanwhile, a LCC compensating network mathematical model and a method of parameter design is put forward. Without adding new electronic components, by using the input fundamental current of LCC networks to compensate the input harmonic current of LCC networks, the instantaneous current value at the switching time of the high frequency inverter is reduced. Thus, zero current switching of high frequency inverter is realized, the switching loss and switching stress of the power tube is reduced, and the overall efficiency of the ICPT system is improved. Finally, the computer simulation analysis and experimental verification of the proposed method are carried out. The simulation and experiment results show that the proposed method is correct and feasible.
