    UPStation GXT 3x1 Chapter 1 – General Description Design Concept 1 GENERAL DESCRIPTION Introduction Congratulations on your choice of the UPStation GXT™ Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment. Upon generation, AC power is clean and stable. However, during transmission and distribution it may be subject to voltage sags, spikes, or complete power failure, which may interrupt computer operations, cause data loss, or even damage equipment.

  • Page 10: Rectifier/power Factor Correction (pfc) Circuit

    Chapter 1 – General Description UPStation GXT 3x1 Design Concept 1.2.2 Rectifier/Power Factor Correction (PFC) circuit In normal operation, the rectifier/power factor correction (PFC) circuit converts mains AC power to regulated DC power for use by the inverter, while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the mains power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the mains is reduced.
