Amantys Announces its New Tj Estimation Evaluation System

The Tj Estimation Evaluation System is a new measurement system developed at Amantys which can estimate accurately both IGBT and diode junction temperatures to within ±5 °C in an operational converter.

The Tj Estimation Evaluation System is an exciting new measurement system developed at Amantys Power Electronics, which can estimate accurately both IGBT and diode junction temperatures to within ±5 °C in an operational converter. It has advanced measurement, data logging, and processing capability, designed for evaluating Amantys Tj Estimation technology and acting as a general-purpose data acquisition system for inverter stack testing.

 

Key Specifications

  • Single power supply input (15 V)
  • Internal isolation for measurement circuits
  • Measurements of upper and lower switches logged at 1 ms rate to USB memory stick
  • Measurement variables recorded:
    • VCE(off), IGBT VCE(on), diode VF for upper and lower switches
    • Phase current, using external current sensor
    • Switching pattern information (pulse timings)
    • Module NTC temperature (if present)
    • Baseplate temperature (up to 2 external lug mounted sensors)
  • On board algorithms calculate Tj of all 4 devices (upper and lower IGBTs and diodes)
  • Continuous calibration of devices
  • Configurable from USB memory stick

The Tj Estimation Evaluation System is supported by the Power Insight Configurator that can display the following information:

  • I-V Curves for the IGBT and the diode
  • Oscilloscope display of the measured parameters
  • Long term display of the measured parameters
