Abstract

In the process of power transmission, changes in system parameters, such as inductance, capacitance and system operating frequency, will cause system detuning and reduce transmission performance. In this paper, a combined control system with frequency tracking is designed for the detuning of MCRWPT system caused by the parameter changes in the non overcoupling region. Only the phase controlled capacitor is added at the transmitter to tune, and at the same time, the phase-locked loop is used to track the frequency, so that the system can quickly recover the resonant state after detuning. This method does not need to add a circuit at the receiving end, which ensures that the system can obtain the best transmission characteristics while reducing the volume of electrical equipment.
