On-line estimation of junction temperatures in power modules
(2014) In CODEN:LUTEDX/TEIE EIE920 20141Industrial Electrical Engineering and Automation
- Abstract
- It is critical for the durability of power modules to maintain low
enough temperature in their components (IGBTs and diodes).
The goal of this project was to examine methods to estimate the junction
temperature of components in an IGBT module in real-time.
After studying literature on the subject, a model was developed using Fostercircuits and feedback from the NTC-thermistor in the IGBT-module.
This model was tested in a simulation with temperature measured at a nearby point and phase currents as inputs. Data for the cooling system (heatsink and fan) was estimated from lab experiments. Information about component characteristics was given in the datasheet for the IGBT-module.
