  • This paper analyses the effects of tuning deviation in the resonant tank of an LCL Inductive Power Transfer (IPT) pickup. It also proposes a method of active tuning which maintains unity power factor at the input to the pickup. By varying the second inductor in the LCL network, variations in the tuning capacitor can be compensated which also acts to increase the output power to the load after the retuning action. The power increase is limited by the available control action and component rating… CONTINUE READING
