ADAPTIVE FREQUENCY CONTROL

UPS uninterruptible power supply control system design

This reference design demonstrates how digital-power techniques when applied to UPS applications enable easy modifications through software, the use of smaller magnetics, intelligent battery charging, higher efficiency, compact designs, reduction in audible and electrical noise via a purer sine-wave output, USB communication, and low-cost overall bill-of-materials.
