The topic of this thesis is the development of a unique, power supply like measurement equipment. The purpose of the device is to ease thermal identification of motor drives, by generating a regulated, arbitrary power output with an accuracy of 1 %.
One of the most important requirement for the device was to connect to the DUT without notably altering the thermal system. This means no high current traces may be cut and thick wires should not be attached to the DUT.
First the chosen heating configuration is explained. The schematic of the device is made in Altium Designer. After the layout is made, the PCB is manufactured and populated. The operation of the circuitry is tested, some modifications are made and their necessity is explained.
To ease the usage of the device a GUI is made in Python. The fully functional device is validated with calibrated measurement equipment, after that the usage is demonstrated with a test measurement.
At the end future development potential and some possible fields of applications are given.
