Abstract:With the rise of Electric Vehicles (EVs), there is a trend for increasing battery pack voltages up to 800V. This results in a need for On Board Chargers (OBCs) to be upgraded to higher voltages to meet these voltage levels. This while still decreasing the size and volume of the system. For current OBCs, the switching frequency is increased, but the voltage is limited to 400 V, while achieving a power density of 3.3kW/L. In this thesis, the goal is set out to design and develop an OBC which can achieve the desired 800 V output with still achieving the high switching frequency and power density. The system has been designed from a system engineering perspective and developed into a lab setup. With partial verification of the desired behavior.
