Single phase online UPS

Block diagram

Overview

Our integrated circuits and reference designs for single-phase online uninterruptable power supply (UPS) help you design reliable and robust hardware with very low input and output total harmonic distortion (THD) and increased efficiency.

Design requirements

Modern single-phase online UPS designs often require:

  • Higher performance and reliable IGBT and MOSFET gate drivers.
  • Innovative battery backup designs with highly-efficient bidirectional topologies.
  • Accurate sensing of voltage and current with or without isolation.
  • Lower total harmonic distortion (THD) over wide load conditions using front-end power factor correction (PFC).
