Overview
This was an internal project designed to be launched on Kickstarter. Unfortunatly, no investors were found to support further development, and the project was shelved. It is a low-voltage uninterruptible power supply (UPS) system designed to provide backup power and ensure continuous operation of critical devices during power outages or fluctuations. Since many house-hold products (PON, Router, NAS, etc) run on low voltage DC, it seemd more efficient to design a UPS that directly provides DC power, avoiding multiple conversion stages.
