TOKO, Inc., a developer/manufacturer of electronic components focused on coil-based products, is demonstrating a self-developed wireless power supply system.
According to the company, wireless power supplies offer many advantages, including convenience, reliability, waterproofing property and dust prevention. This technology has found widespread applications in various fields, particularly cordless phones. TOKO has shipped a cumulative total of more than 12 million wireless power supply products. It expects to have them employed for small portable devices such as mobile phones and digital cameras. TOKO has joined the Wireless Power Consortium (WPC) to step up R&D in this area.
Based on its own technology, the company is pushing ahead with improvement in transmission efficiency. It states that it has displayed a particular strength in the coil portion that is the key to wireless power supply, achieving coil-to-coil transmission efficiency of 93% by taking advantage of its winding and RF techniques in which TOKO is strong. The company is demonstrating a wireless power supply that uses a 4.0W class transmission cable.
