非接触給電の研究が多様な視点で行われている.筆者は,磁気結合を利用した非接触給電の新たなしくみや利用法を研究してきた.磁気結合給電では,送受電コイル間の結合係数kが重要な指標であり,受電電圧や受電電力,効率等の重要な性能を決定する.従って機器のフリーポジションや移動中での良好な非接触給電を提供するにはkの数値を規定値範囲に維持することが重要である.またkの数値を給電中に知ることは最適な制御が可能になり,給電性能を向上できる.既に筆者は,S-SP型で交流抵抗負荷の場合において,送電側端子電圧振幅の単独の情報で精度の高いk推定が可能なことを実証した.一方,実用回路では受電側で整流・平滑回路を経て直流電圧を出力する.本稿では,この実用回路にて負荷電圧の変化抑制効果と送電側センス回路での良好なk推定精度を確認したので報告する. |

Research on wireless power transfer is being conducted from various perspectives. The author has studied a novel mechanism and usage of wireless power transfer using magnetic coupling. In the magnetic coupling feed, the coupling factor k between the transmitting and receiving coils is an important index, and determines important performance such as received voltage, received power, efficiency, etc. Therefore, it is important to keep the numerical value of k within the specified value range in order to provide a good free position of the equipment, and good wireless power transfer during the movement. Also knowing the numerical value of k during power supply makes it possible to optimally control and improve the power supply performance. The author has already demonstrated that in the case of S-SP type and AC resistance load, it is possible to estimate k with high accuracy by using information on the transmission terminal voltage amplitude alone. On the other hand, in a practical circuit, a DC voltage is output through a rectifying and smoothing circuit on the power receiving side. In this paper, it is reported that this practical circuit demonstrates the change suppression effect of DC load voltage and the high accuracy of k estimation in the sense circuit on the power transmission side. |
