Single phase online UPS

Single phase online uninterruptible power supply (UPS) system integrated circuits and reference designs

Description

Our integrated circuits and reference designs for single phase online 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 single 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.

Three phase UPS
