要約(英語): In recent years, inductive power transfer systems with resonance have been studied. However, additional DC-DC converters are required on the primary and secondary sides of such inductive power transfer systems. The roles of these DC-DC converters are controlling the output power and maintaining the transmission efficiency because the transmission efficiency strongly depends on the load. Moreover, high-accuracy capacitances for resonance with a high-voltage rating are required. These features prevent cost reduction and improvement in the system efficiency. In this paper, a non-resonant inductive power transfer system based on the principle of a dual active bridge converter is proposed in order to overcome above problems. The proposed system has two full bridge inverters on the primary and secondary sides of the non-resonant inductive power transfer system. This configuration reduces the primary current at a rated power in comparison with a conventional non-resonant inductive power transfer system. The output power is controlled by the phase difference between the primary and secondary voltages of the transmitting coils. The phase difference is determined using a hill-climb method by a secondary controller. An experimental verification showed that the proposed system achieves a maximum efficiency of 94.1% with an output power of 0.84kW.
