Improvement of non-contact power supply device

Improvement of non-contact power supply device

A device that transmits power without contact through conductors such as electric wires! There is no contact with conductors!

Our company has been engaged in the research and development of non-contact power supply devices using electromagnetic induction since 1998. The initial product we developed was a small-capacity device in the tens of watts range, which was commercialized and sold for powering household illumination lamps and decorations. Subsequently, to expand applications, we have developed large-capacity products ranging from hundreds of watts to 3 kW. This document provides an overview of Aichi Electric's "non-contact power supply device" and highlights the improvements made this time. We invite you to read it. [Contents (partial)] ■ Introduction ■ Overview of the non-contact power supply device ■ Operating principle of the non-contact power supply device ■ Conventional non-contact power supply device ■ Improved non-contact power supply device *For more details, please refer to the PDF document or feel free to contact us.

Elevator parking lot EV automatic charging device (patented technology)

Elevator parking lot EV automatic charging device (patented technology)

The electric connector (power supply) for EV charging is automatically attached and detached from the pallet in the multi-story parking lot. There is no need to route wiring or cables.

The electric connector will automatically attach and detach to the EV charging pallet in multi-story parking lots and similar locations. It can accommodate connections in both horizontal and vertical directions. Additionally, installation outdoors is not an issue. We will design and manufacture custom solutions based on the customer's equipment situation. We can also develop products individually for multi-story parking lot manufacturers.

Wireless power transmission <Application 1>

Wireless power transmission <Application 1>

Introducing the applications of wireless power transmission that Adtex is working on!

The "wireless power transmission" that we are working on is suitable for charging items that cannot be stopped accurately, such as automated guided vehicles. It is also suitable for powering wet items or those that cannot use electrical contacts (such as in seawater). It features the absence of sensors to sense the positions of the transmission coil and the receiving coil, no need for signal transmission between the transmission side and the receiving side, and no need for digital control devices. **Features of Wireless Power Transmission** - No sensors to sense the positions of the transmission coil and the receiving coil - No need for signal transmission between the transmission side and the receiving side - No need for digital control devices - Large margin for positional misalignment between the transmission coil and the receiving coil - Transmission distance is approximately equivalent to the coil size *For more details, please download the PDF or feel free to contact us.*

Wireless power transfer technology

Wireless power transfer technology

Solve the slip ring wear problem of turntables and rotating platforms! Achieve stable operation.

Our "wireless power transmission technology" is a unique technology that overcomes the weaknesses of conventional wireless power transmission. It is robust against distance variations and achieves highly practical power delivery. Even with vibrations from a rotating platform or positional shifts, it maintains stable power transmission. It can operate stably in real-world environments where other technologies have struggled. Additionally, while traditional methods saw significant power fluctuations with changes in distance, our technology transmits a constant power across the entire range. It features simple control and a highly reliable design. [Features] ■ Exceptionally strong against distance variations ■ Same power from distance 0 to the limit ■ Transmission distance is approximately the size of the coil *For more details, please download the PDF or feel free to contact us.

Off-grid power supply device for hybrid energy storage systems OFGSⓇ-H

Off-grid power supply device for hybrid energy storage systems OFGSⓇ-H

Switching not required (always powered type) for 'Always and In Case Free' - Towards a phase-free environment for 'Disaster Preparedness Without Preparation' OFGSⓇH Series.

The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a transformer and control/protection integrated switching panel/transmission system developed to maximize the use of solar storage batteries during both normal and power outage conditions. The OFGS®-H series is a constant power supply system designed for hybrid storage battery systems. During power outages and restorations, it allows for seamless power supply and autonomous operation without the need for manual intervention, thanks to the automatic switching mechanism of the dedicated transformer. This system fully utilizes the capabilities of hybrid PCS without the need to switch between grid (GRID) and off-grid (Off GRID), enabling the realization of corporate renewable energy initiatives such as BCP measures, phase-free operations, and RE100, while addressing installation conditions related to grid connection. It facilitates the construction of a storage battery system that provides clean energy through natural energy (solar power) and off-grid (independent of the power grid) supply, regardless of normal or emergency situations. By packaging "three-phase transformers" + "Scott transformers (for specific single-phase loads)" + "protection devices" + "control devices" into an 'all-in-one package', installation and construction time can be significantly reduced.
