Uninterruptible Power Supply (UPS)

The latest Uninterruptible Power Supplies (UPSs) must maximize the efficient storage and conversion of energy for use during power outage occurrences. To accomplish this task, UPS designers must select semiconductor components that provide tangible gains in energy efficiency without undesirable performance trade-offs. AEM manufactures discrete semiconductor solutions designed to minimize total conduction losses for UPS applications.
