Three phase UPS

Products and reference designs

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.

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.
