Overview

The TIDA-00195 reference design consists of a 22kW power stage with TI’s new reinforced isolated IGBT gate driver ISO5852S intended for motor control in various applications. This design allows performance evaluation of the ISO5852S in 3-phase inverter incorporating 1200V rated IGBT modules of current ratings ranging from 50A-200A.

Some of the important functionality and performance evaluated are short circuit protection using DESAT detection, Soft-shutdown, effectiveness of the Active Miller Clamp at different inverter dv/dt, and ESD/EFT performance of IGBT gate driver at system level derived from adjustable speed electrical power drive systems (IEC61800-3). Piccolo launch pad LAUNCHXL-F28027 is used to generate the PWM signals required for controlling the inverter.

Features
  • 3-phase inverter system with:
    • 1200v rated IGBT module of current ratings from 50A-200A. (supporting multiple vendors)
    • 7 reinforced Isolated IGBT gate drivers – ISO5852s with working voltage isolation of 1.5kVrms with Minimum CMTI of 50 kV/μs
  • Incorporates protection against over current and false turn ON using:
    • DESAT detection
    • Soft shutdown
    • Active Miller clamp
  • Meets IEC61800-3 EMC immunity requirements:
    • +/-8kV ESD CD per IEC 61000-4-2
    • +/-4kV EFT per IEC 61000-4-4
  • On board half-bridge isolated power supply generating +16v/-8v for gate drivers with a provision to operate gate drivers with unipolar or bipolar supply with external BJT / MOSFET buffers
  • Gate driver input can be configured for inverting/Non inverting operation
  • Option to evaluate the system with:
    • Twisted pair cable between the gate driver and IGBT
    • External capacitance between gate and emitter

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
