在这项研究中，感应电能传输系统（IPT）的设计和开发的挖掘机，这将是在高气压下工作。在传统的挖掘机系统中，电力通过电车线供应。由于挖掘机在高气压下工作，接触线和伸缩臂之间的接触可能是由于火花引起火灾的原因。在所提出的系统中，在初级侧上的串联谐振电容器和在次级侧上的并联谐振电容器被用来抵消漏感。通过使用串并联补偿，负载电压理想地是恒定的，而不管负载波动。然而，当绕组电阻和谐振参数的误差不能被忽略时，恒压特性可能劣化。因此，谐振参数的设计必须考虑误差。本文提出了考虑绕组电阻等参数误差的电压比图谐振参数设计方法。实验结果表明，电压波动小于4.3%与开发的15千瓦的IPT系统。此外，即使当感应电动机的输出功率从5到15 kW变化时，也能保持恒压特性，反之亦然。
In this study, an inductive power transfer system (IPT) was designed and developed for an excavator, which will be operated under high air pressure. In the conventional excavator systems, power is supplied through trolley wires. The contact between the trolley wires and a pantagraph may be a reason of fire due to a spark because the excavator works under high air pressure. In the proposed system, a series resonance capacitor on a primary side and a parallel resonance capacitor in a secondary side is used to cancel out the leakage inductance. By using the series–parallel compensation, the load voltage is ideally constant regardless of load fluctuation. However, the constant-voltage characteristic may degrades when a winding resistance and an error of the resonant parameter cannot be ignored. Thus, the resonant parameters must be designed considering the error. This paper proposes the design method of the resonant parameter with the voltage ratio maps considering the error of the parameter including the winding resistance. The experimental results confirmed that the voltage fluctuation is smaller than 4.3% with a developed 15-kW IPT system. Furthermore, the constant-voltage characteristic is maintained even when the output power of an induction motor changes from 5 to 15 kW and vice versa.
