eBoost™ - GE Energy

1 GE. Digital Energy eBoost . Guaranteed Higher UPS Efficiency Energy consumption is a critical issue for IT Technology breakthroughs organizations as their data center Energy Up to 99% UPS efficiency demands continue to grow. Their goal is Compliant to ITI (CBEMA) curve during undervoltage to reduce cost and keep the datacenter events running. Up to 3 MVA UPS capacity using Redundant Parallel Architecture (RPA). Magnetizing the output transformer ensures a < 2ms IT organizations can reduce Energy transfer time consumption and costs without sacrificing Static bypass inductor for filtering utility power reliability with GE's eBoost technology. Battery trickle charge in eBoost operating mode What is eBoost? e = high efficiency (up to 99%). Boost = fast power transfer (<2ms). imagination at work Customer benefits 80% reduction in UPS losses eBoost System Energy cost savings Reduced heat (BTU) generation Energy savings from reduced cooling Extended UPS component life User-programmable scheduling Reduced acoustical noise double conversion Inductor Static bypass Power flow Mains Z Load Rectifier Inverter Output transformer Battery Capacitor During traditional operation the UPS runs in double conversion mode.

2 Both the rectifier and the inverter are continuously operating, resulting in an efficiency of 92-94%. eBoost single module Power flow Inductor Static bypass Mains Z Load Rectifier Inverter Output transformer Battery Capacitor During eBoost operation the load is supplied directly by the mains, via the static bypass circuit. This provides an efficiency up to 99%. In case the mains voltage is out of tolerance, the UPS will immediately transfer the load to the inverter in < 2ms. The < 2ms is achieved by our patented* technology to magnetize the output transformer. The output transformer provides galvanic isolation between inverter and load. The static bypass inductor filters the input AC power during eBoost operational mode. * Patent No. 7,372,177. eBoost in Redundant Parallel Architecture (RPA). Power flow UPS module #1. Z.
