BACHELORTHESIS: MODEL-BASED ANALYSIS OF THE PRECHARGING CIRCUIT OF AN IGBT RECTIFIER TOPOLOGY REGARDING THE BEHAVIOR AT LIMITS
Put the skills you have acquired during your studies into practice and complete your final thesis with us.
For many converter topologies with DC link, precharging is required. This can be solved in different ways, from a simple series resistor up to a separate control with power semiconductors. The critical thing in this application is the behavior at the voltage or power limits. Due to nonlinear components and aging, even the simple system becomes a complex problem. The aim of this thesis is to derive characiteristics and dependencies to gain robust information on the limits and adaptability of these applications.
