Variable output ±5KV or 10KV high voltage power supply for inkjet printers; high voltage power supply for generating static electricity.
【Issues / Results】 ■ The design quality of existing products is poor (1/3 have operational failures) → Analyze existing products, extract issues, and create a new design. ■ High noise levels → Identified the cause as control jitter, improved the control phase loop. Added slits to the circuit board and improved the gap. Reduced leakage current. ■ Want to change the output voltage → Use transformer feedback winding for output voltage feedback control. ■ Want to support ±5KV and 10KV specifications on the same circuit board → Design patterns to accommodate both specifications. ■ Want to add a DC400V power supply on the same circuit board → Addressed considering noise and gap. *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.
