AC drive power stage module

Block diagram

Overview

Our integrated circuits and reference designs help you create an efficient, fully protected power stage module for alternating current (AC) drives. Our analog and embedded processing products enable improved motor control performance and exceed isolation and EMC requirements per IEC standards.

Design requirements

AC drive power stage modules often require:

  • Non-isolated and isolated gate drivers with high common mode transient immunity (CMTI) and built-in protection.
  • Precise current and voltage sense for torque control in sensorless operation.
  • Robust overcurrent protection against short circuit and shoot through events.
  • Efficient non-isolated and isolated power supplies with tight regulation.
