【摘 要】
In a multiple excitation unit wireless power transfer system, power control flflexibility is a
critical feature. To develop a system with environmental sensing capability and a smart power distribution
strategy, a cooperative control method is proposed for the excitation units. A multiple coupling coeffificient
identifification method was developed by utilizing the DC information of each excitation unit. Furthermore,
a bi-operation mode with adaptive area division is proposed to achieve maximum effificiency in the optimum
coupling area and to satisfy the fundamental power requirement for a weak coupling area. In the identifification
and control implementation process, this method is easy to implement and the response speed can be
guaranteed because only the DC input current and the duty cycle of the DC regulator information are required.
In addition, the proposed approach was evaluated based on experimental analysis.
