At HPE, a 20 kV / 400 A solid-state modulator using SiC MOSFETs is currently under investigation. In this project, you will simulate the influence of cell-driving jitters on the output pulse of the pulse modulator. For that, you will be working with FEM-based 3D time-domain models. - Electrical Engineering

The main part of this project is to develop a Matlab program which calculates the winding losses in Litz wire considering 2D magnetic field effect. This program should be computational efficient. To evaluate the calculation method the FEM simulation needs to be also performed. - Electrical Engineering

In this project you will design transformer prototypes for winding loss measurement. You will calculate the basic parameters such as the core size, and the number of turns for a given set of specifications. Based on your results, you will select off-the-shelf cores and litz wire for the transformer. To validate the design, FEM simulations are implemented and in case of a master thesis measurement are performed on prototypes. - Electrical Engineering

In this thesis, you will develop a control scheme for operating points within the operation limits of the VSI of the HT AC/AC auxiliary converter in series to the transformer secondary winding. The development of the control scheme and the analysis of the VSI will be based on simulations in MATLAB/PLECS. - Electrical Engineering

In this thesis, you will compare and select IGBT modules for the VSI of the HT AC/AC auxiliary converter in series to the transformer secondary winding. Further, you will calculate the semiconductor losses based on a thermal model for the selected switches. Additionally a design of the heat sinks and the DC-link capacitance will be part of this work. The design of the VSI components will be based on simulations in MATLAB/PLECS. - Electrical Engineering

Liebe Masterstudierende
Die Forschungsgruppe des neuroradiologischen Departementes des Universitätsspitals Zürich (Leitung: PD Dr. Lars Michels) sucht ab Juni 2022 ein*e Forschungspraktikant*in mit Option auf Masterarbeit. In dieser Studie untersuchen wir die bisher wenig erforschte neurologische Erkrankung Visual Snow und die Möglichkeit von fMRI Neurofeedback Training als Therapiemethode. Das Projekt beinhaltet fMRI, DTI, MR-Spektroskopie Messungen (MRS) und psychophysische Tests.

Electrostatic artificial muscles show great potential for the use in bioinspired robots. Most of these actuators require AC driving voltages in the range of several kilovolts. Therefore, you should develop a compact HV power supply in collaboration between the Soft Robotics and the HPE lab. - Electrical Engineering
