The imperfect coupling (or misalignment) between the inductively coupled coils in an inductive power transfer (IPT) system is a major problem of the wireless battery charging. This problem causes decreasing and fluctuations of the system efficiency and load power (or load voltage). In this paper, a new approach was introduced to deals with such a problem. The proposed approach based on the maximum power point tracking (MPPT) and load power/voltage regulation (PR/VR). The MPPT technology based on the impedance matching (IM), where the tuning capacitances are still varying to keep the resonant frequencies of the coils equal to the inverter switching frequency (fs). The proposed PR/VR was achieved based on the duty cycle control of the inverter; the fuzzy logic controller (FLC) was used to achieve that.
