title: Dataset from switching loss measurement test bench by opposition method

description: 📝 Description

A detailed description of the dataset:



Purpose: To share preliminary data measured from an open source, collaborative test bench

Content: Measurements (data points, oscilloscope pictures, measured DC values with multimeters) and configuration file, included post processed data to extract Turn OFF switching losses

Sources: Measured at Laplace Lab in Oct. 2025, with IRFP 240 200 V 20 A Si MOSFET, and implemented in two half bridges from Infineon  EVAL-1ED3122Mx12H

Target Audience:  researchers, developers, general public, people involved in switching loss analysis and design of power converters

The dataset has been generated experimentally by an automated test bench, build at Laplace, in collaboration with LAAS-CNRS and Owntech.

We thank all persons involved in this project since 2024: professors, scientists, engineers, students at Université Toulouse.

 

🗃️ Dataset Structure

The whole dataset is compressed in a single ZIP file. The config file used to generate the dataset is included in a separate json.

Folders

 




Folder Name
Description




[excel]
[Extracted values from the DC measurement of DC bus voltage, and DC current ]


[lib]
[Includes a Python file to further load data obtained from the oscilloscopes]


[PhaseShift]
[Raw data obtained for several sweeps of switching frequencies, DC bus Voltages, max inductor current]


[sauvegarde]
[Post processed data to extract Eoff from raw data]




The zip file also contains oscillosope pictures and 4 channel data acquired at a lower sampling frequency, for one try (fixed DC bus voltage, stepped max inductor current)
