Modeling of an IGBT and a Gate Unit
The purpose of this master thesis was to create a model of an IGBT in a single
pulse test circuit and connect this model to a model of a Gate Unit. The IGBT
model and the single pulse test circuit were both implemented in MATLAB and
the Gate Unit was implemented in Simulink. The purpose of this model was
to test the actions of the gate unit, so that the initial tuning could be done
before going to the lab. Since no tests were performed in the lab, it was not
possible to see how much of the testing that could have been done by simulations.
However, the actions of the IGBT model much resembled the actions of the real
component, even though some drawbacks were clear, such as the lack of tail
current and tail voltage. These comparisons could be made between simulated
characteristics and recordings from a previous test with the same component.
