Fluxgate Magnetic Current Sensing Reference Design with High Linearity for 3–Phase Inverters

Description

The TIDA-00905 reference design provides a reference solution for accuracy, high linearity and the galvanic isolation required for current measurement in three phase inverters using closed-loop fluxgate magnetic current sensors. It consists of magnetic core with compensation winding interfaced to dr

Features
  • Designed to accurately measure three phase inverter currents up to 50ARMS (nominal) and 150A (maximum) 200 kHz bandwidth, closed-loop current sensing using magnetic module and fluxgate sensor (DRV421) to enable low propagation delay
Applications
  • String Inverters
  • AC Inverter & VF Drives
  • Micro Inverters
  • AC Charging (Pile) Station
  • Brushless DC Motor Drives
  • AC / DC Power Sources
