Wireless power transmission board capable of delivering 30W of medium power.
【Issues / Results】 ■ The mainstream Qi standard cannot achieve more than 5W → Independently developed a 30W type aimed at medium capacity. ■ A transmission distance of 20mm is desired → Tuned the resonant capacitor and frequency to accommodate a 20mm gap. ■ It takes 5 seconds to start with other manufacturers' products → Achieved a startup time of 0.3 seconds. ■ I want it to stop automatically → Safely stops power transmission during abnormal conditions or when the receiving coil is not found. Reduces reactive power and minimizes the risk of magnetic interference. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Despite being located in the remote Wakayama Prefecture, we provide technical support to strong venture companies that aim to create new value in the domestic market and among leading manufacturers. <Business Areas> 〇 Analog and Power Electronics Circuit Design If you have challenges related to the efficiency of analog circuits (such as power supplies, motors, pressure sensing, or feedback control), stability or improvement of output values, or noise countermeasures, please feel free to consult with us. We are also skilled in tuning after the production of actual devices. 〇 PCB Design, CAD, Verification, and Documentation With a strong foundation in electronic circuit knowledge, we have extensive experience in PCB design and CAD (OrCAD/CR8000). We also have a track record in verification and documentation, including responses to FMEA and FTP. Regarding verification documents, we actively provide comparative data before and after tuning and conduct reviews (explanations) through meetings via web or other means. Additionally, we are flexible in providing partial support for verification, drawing checks, tuning, and other areas, so please feel free to reach out to us.
