System and method for efficient power distribution and backup
Granted patent · Australia · publication AU2014290201B2
Overview
A parallel uninterruptible power supply system that eliminates expensive active switching components between power sources and UPS units. Conventional backup power systems require active switches and complex synchronization to connect multiple power sources to UPS devices, adding cost and creating failure points that cause downtime during repairs. This invention uses direct connections—wiring with no active components between the power sources and UPS inputs—allowing two or more UPS units to operate in parallel while drawing from independent AC mains and generator sources. Each power source has its own selector switch to choose between utility power or generator power, but no active switches exist between the selector and the UPS units themselves. This approach eliminates expensive synchronization hardware, reduces failure modes, simplifies scaling to additional loads, and maintains power delivery even if one source fails, since the other power source continues supplying both UPS units.
