System and method for efficient power distribution and backup
Granted patent · Canada · publication CA2918450C
Overview
A parallel uninterruptible power supply system in which multiple UPS units are connected in parallel to independent power sources without intervening active switches. Conventional systems place expensive active switches between power sources and UPS inputs to manage the connection and require synchronization across feeders. This system instead feeds each pair of UPS units directly or through passive switches from two or more independent power sources. If one power source fails, the other continues delivering power through the UPS units to the connected loads. By eliminating active switching components, the system reduces cost and complexity, removes synchronization overhead and failure points, and enables linear scaling—additional UPS units and loads can be integrated without redesigning the switching infrastructure.
