title: A Coil Array IPT System for Autonomous Underwater Vehicle (AUV)
abstract: For a long time, providing a stable, safe, and efficient power supply for underwater electromechanical equipment has always been a concern in deep-sea exploration. Compared with the complicated docking mechanism, potential safety hazards, and expensive price of traditional wet-mate connectors, wireless power transmission (WPT) technology can transmit energy without any electrical contact between the power supply and the electrical equipment, which provides an effective solution to the aforementioned drawbacks of wired charging. There are many uncontrollable factors in the seawater working environment. Therefore, this topic takes the equivalent circuit and magnetic field distribution as the theoretical basis to study the energy transmission characteristics of underwater WPT and proposes corresponding improvements and solutions to the current problems and deficiencies. Especially for the unstable output voltage of the receiver and excessive magnetic flux density at the internal of AUV. language of the presentation: English | |||||||

title: Design of a power transmission coil for non-contact power supply to small devices
abstract: Contactless power transfer is the wireless transmission of power from a power transmitter to a power receiver via a magnetic field. As such, it offers the convenience of not needing an electrical outlet, and research on contactless power transfer to smartphones, electric vehicles, and other devices is underway. Among them, contactless power supply to IoT devices and mobile terminals is demanded by many users. However, since IoT devices and mobile terminals are likely to be arranged in a variety of ways, it has not yet been put to practical use. The reason for this is that the distance between the power receiver and the power transmitter and the complexity of their arrangement significantly reduces the power supply efficiency. In this paper, we present our current results on the design of power transmission coils for wireless power supply to small devices. language of the presentation: Japanese 発表題目:小型機器への非接触給電を目的とした送電コイルの設計 発表概要: 非接触給電は送電器から受電器へ磁界を介して無線で電力伝送を行う。そのため、コンセントを必要としない利便性があり、スマートフォンや電気自動車等への非接触給電の研究が行われている。その中でもIoT機器やモバイル端末への非接触給電は多くのユーザーから求められている。しかし、IoT機器やモバイル端末は配置が多様になることが考えられるため、実用化には至っていない。理由は受電器と送電器の距離や配置が複雑になることで給電効率は著しく低下するためである。本研究では小型機器へのワイヤレス給電を目的とした送電コイルの設計について現状の成果を発表する。 | |||||||
