Abstract
Voltage sags, transients, and momentary interruption of power together cons titute 92% of the power quality problems encountered by typical industrial customers. The series-parallel-connected Dynamic Sag Corrector (DySC) provi des statistically significant protection at greatly reduced cost. The DySC is rated from 1.5-kVA one phase to 2000-kVA three phase and features a pate nted single-stage power conversion circuit with minimal stored energy. A un ique circuit allows operation with opened upstream circuit breaker. This pa per presents a detailed discussion of DySC operating principles and validat ion of performance. It also provides conditions under which this new catego ry of product can be applied.
