Design of a High-Voltage Measurement System for Characterizing MLCC Derating Effects

To investigate the derating effects of ceramic capacitors (MLCCs), a measurement system is to be developed that can generate test signals with variable bias voltage and different signal frequencies. Additionally, it should allow for precise determination of the effective total capacitance under these operating conditions. The focus is on DC voltages up to 200 V. Using this system, derating effects will be analyzed and evaluated exemplarily.

Gate Driving Techniques for Hybird 48V DC-DC Converters

Modern computing units in data centers require highly efficient 48V:1V DC-DC converters with high power density. Hybrid switched-capacitor DC-DC converters represent a class of promising topologies. The aim of this student work is to develop suitable gate driver concepts for hybrid switched-capacitor DC-DC converters in 48V applications. A particular focus is on generating the gate driver supply for switches with flying source potentials, which are common in this class of topologies.

Implementation and Optimization of an Error Correction Application Based on a Transport-Triggered Processor Architecture

In this Bachelor's thesis, a Reed-Solomon-based error correction application shall be implemented in C and shall be optimized for a Transport-Triggered processor Architecture (TTA). By using the TTA-Based Co-Design Environment (TCE) from the University of Tampere, Finland, specializations to the base architecture are made and extensive analysis and profiling possibilities for application and processor optimizations are provided.
