Master's Thesis BMW: Simulation and Hardware Implementation of a DC/DC Converter for Highly-Available Automotive Energy Systems of Driverless Electric Vehicles
A 400/12 V phase-shift DC/DC converter should be realized in hardware for the further development of a test bench and for the evaluation of system-inherent disturbances. The starting point is a switching model Plexim PLECS model.
Keywords: Modeling, Simulation, Hardware, DC/DC converter, phase-shift, dual active bridge
Dynamic and safety-relevant electrical components in automotive energy systems increase the functional requirements to the energy and power supply. A reduced availability of energy or power within energy systems of self-driving vehicles is particularly safety-critical.
Elevated power peaks could damage electrical components, reduce their performance, lead to malfunctions or impair the energy systems stability.
One central component of the energy system is the 400/12V DC/DC converter. Its task is the low-loss energy and power transfer between high-voltage energy system (powertrain, battery storage) and low-voltage energy system (steering, brake, etc.). A 400/12 V phase-shift DC/DC converter should be realized in hardware for the further development of a test bench and for the evaluation of system-inherent disturbances. The starting point is a switching model Plexim PLECS model.
