Evaluate IGBTs from ABB with Web-Based Simulation

March 01, 2015 by ABB

This article introduces ABB Semiconductors' SEMIS, a web-based simulation tool which is embedded in ABB's homepage for evaluating IGBT modules' performance.

SEMIS offers a quick and easy way to evaluate the performance of IGBT modules from ABB under various operating conditions. All you need is a web browser on a computer or mobile device. You can immediately start a simulation without the hassle of installing software or creating a user account.

The first simulation model is a typical voltage-source inverter circuit supplying an RL-load. Nearly all circuit properties such as the load characteristics, the cooling system and the PWM control can be configured to match the values of your specific application.




From a list of semiconductors choose an appropriate IGBT module for the desired DC voltage and load current. By selecting multiple IGBT modules, the device losses and temperatures can be compared directly against each other. The simulation results are displayed as scope waveforms and data tables. In the scopes you can zoom into the transient waveforms of voltages, currents and temperatures. For a quick summary, the average switching and conduction losses as well as the maximum junction temperature are listed in tabular form.

SEMIS is based on PLECS, the leading simulation software for power electronic systems. On the ABB homepage, the semiconductor models used in SEMIS are provided as downloadable files. This allows you to continue the simulation offline on your computer. By using original thermal models developed by ABB you can easily calculate accurate switching and conduction losses. This will help you to design optimum cooling solutions that keep junction temperatures within specification. The offline simulation can be performed with a free demo or trial license of PLECS, or with a fully licensed PLECS installation.
