    1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Hardware Hardware This section provides a short description of the board hardware. First, it explains the power circuitry, the main components and the connectors. Then, the application of the recommended accessories is discussed.
  • Page 6: Recommended Accessories

    1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Hardware An experimental analysis of a device’s switching behavior requires oscilloscope measurements of the gate voltage, the collector-emitter voltage as well as the collector current. While voltage measurements are straightforward, current measurements are more difficult to do, particularly in the presence of steep current slopes.
  • Page 7 1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Hardware Table 1 compares waveforms as well as switching losses measured with the metal foil SMD resistor and the coaxial shunt at various temperatures and voltages. As all measurements are done with exactly the same semiconductor devices, the differences can be attributed to the different current sensors.

It includes the relevant components of the circuitry and highlights the most important part labels which consist of a letter and a three-digit number.
  • Page 11: Adjusting And Monitoring The Heat Sink Temperature

    1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Usage Adjusting and monitoring the heat sink temperature 3.1.4 Switching losses are not only measured at room temperature but also at temperatures of 100°C and above. Consequently, a measurement setup must offer the possibility to adjust and monitor the case temperature of the devices under test.
  • Page 12 1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Usage and current. Measuring the current and voltage waveforms of the devices on the oscilloscope gives an impression of the switching behavior and allows a calculation of the switching losses. In order to maximize the accuracy and minimize the effort, it is recommended to make oscilloscope measurements on the low side device S : use configuration (1) to study the IGBT and configuration (2) to study the...
  • Page 13: Switching Loss Measurements

    1200V HighSpeed 3 IGBT in TO-247PLUS Evaluation Board User Manual Usage Switching loss measurements 3.2.2 Switching losses can be determined using a double pulse test. It generates both a turn-off and a turn-on event by applying two consecutive pulses on the gate of the switch – hence the expression double pulse. Due to the fact that the circuit is not operated in a continuous fashion the self-heating of the semiconductors and the inductor is negligible.

  • Page 16: Substituting Parallel 40A Devices With A 75A Device

    Examples Substituting parallel 40A devices with a 75A device With IKQ75N120CH3 and IKY75N120CH3 Infineon has pioneered assembling 1200V/75A IGBTs and full-rated diodes inside packages with a footprint of a standard TO-247. One interesting aspect of such high current ratings is the potential to limit the number of parallel devices. This section demonstrates that two parallel 40A IGBTs can be substituted by a single 75A IGBT.
