Servo drive power supply module

Block diagram

Overview

Our integrated circuits and reference designs help create reliable, efficient power supply modules to generate common DC bus for powering servo drives. Our analog and embedded processing products enable uni- or bi-directional power transfer and exceed isolation and EMC requirements per IEC standards.

Design requirements:

Servo drive power supply modules often require:

  • Precise grid voltage sensing to enable synchronization and power factor control.
  • High-bandwidth, precise current sense to meet current harmonics per IEEE519.
  • Accurate DC voltage and current sensing for tight regulation and protection.
  • Efficient and reliable performance under a variety of operating conditions.
