• SUMMARY The switching frequency affects the efficiency of a secondary‐side converter that is configured with a diode bridge rectifier connected to a DC‐DC converter in an inductive power transfer (IPT) system. The efficiency characteristics for the switching frequency of a secondary‐side converter were analyzed theoretically in order to establish a highly efficient control scheme the controls the switching frequency of the converter. A control scheme is proposed in which the switching frequency of the secondary‐side converter is controlled according to the efficiency characteristics. The validity of the proposed control scheme was clarified through experiments. The results showed that the proposed control scheme improved the efficiency of the IPT system by 3.4 points compared to the conventional control scheme.
