System and method for efficient power distribution and backup
Granted patent · Canada · publication CA2883229C
Overview
A parallel-connected backup power system that eliminates expensive active switching components between power sources and uninterruptible power supplies. Conventional UPS systems require active switches between the main power grid (or generators) and each UPS unit to manage the transition between normal and backup power—these switches are expensive, must be sized individually for each system, and represent a critical failure point that takes the entire system offline if they break. This invention connects multiple UPS units directly to two or more independent power sources without active switches in between, allowing the UPS units to automatically receive power from whichever sources are available. If one power source fails, the others continue supplying power to the loads without interruption. The system is simpler to scale since new UPS units can be added without redesigning switching infrastructure, and it reduces overall costs by eliminating active components, their associated synchronization requirements, and their failure modes.
