AC Drive Power Stage Module

AC Drive Power Stage Module System Solutions from Texas Instruments

Description

Variable frequency AC drive power stages for AC inputs (200V to 690VAC) typically employ three half-bridges with IGBT or MOSFETs while faster switching inverters already implement GaN FET or SiC FET power switches. The gate driver has a major impact on efficiency, protection and reliability of the power stage. Accurate phase current and voltage sensing impact AC Drive performance. Shunt, hall-effect or flux-gate based current sensors are typically used and require accurate and low-drift current sense amplifiers, delta-sigma modulators or A/D converters. The power stage requires basic or reinforced isolation with high EMC immunity depending on the AC Drive system voltage. TI reference designs and solutions for AC drive power stage help solve these system design challenges.

  • Basic and reinforced capacitive isolation technology with industry leading CMTI, lowest propagation delay and high EMC immunity
  • Isolated and non-isolated gate driver with high CMTI, lowest propagation delay and built-in protection
  • Accurate current and voltage sensing with isolated precision delta-sigma modulators and amplifiers
  • Efficient isolated and non-isolated power supply solutions
