Three phase UPS

Block diagram


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

Design requirements

Modern three-phase 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 THD over wide-load conditions using front-end power factor correction.
