Low-loss solutions for UPS power systems
To mitigate these losses, energy-efficient UPS systems employ a power management system that precisely controls every pulse of the switching cycle, optimizing the inverter's switching for specific load types and load levels. UPSs are part of a data center's electrical distribution system, which includes utility or generator-supplied power, building switchgear and transformers, and Power Distribution Units (PDUs). However, energy loss within these systems can lead to inefficiencies and higher operational costs. Fortunately, there are effective strategies to minimize this loss. The core value of an Uninterruptible Power Supply (UPS) is “Energy storage during normal operation + Voltage regulation, seamless switching to battery power when the mains supply fails”. By employing the four key components of “Rectifier – Energy Storage – Inverter – Switch,” UPS provides. I. Double conversion on-line UPS diagram used as representative model. Other topologies will have similar solution needs at common power levels.
