“…This topology allows a very efficient and compact design, in particular if wide-bandgap power semiconductors are applied [14], [24]. However, given a rated dc-link voltage of 400 V the minimal battery voltage cannot be set below 100 V without jeopardizing the efficiency of the dc-dc converter.…”

“…These passive components can be dimensioned smaller with increasing switching frequency, reducing weight, size and cost of the overall system [24], [26]. Despite the higher prices of WBG semiconductors in comparison to silicon semiconductors, the overall system cost in WBG based power converters can be reduced significantly due to the size reduction of passive devices.…”

“…Despite the higher prices of WBG semiconductors in comparison to silicon semiconductors, the overall system cost in WBG based power converters can be reduced significantly due to the size reduction of passive devices. The smaller the size, the less cost intensive materials like high-performance ferrite, copper or litz-wire are required [24]. In addition, the higher power density results in a reduced weight of the drive train and thus contributes to a higher driving range of EVs.…”

“…Especially in converters with GaN devices, which can operate at elevated MHz switching frequencies, the magnetic components often enforce a limit on the total power density, because the magnetic losses can not be dissipated easily [26]. To overcome this issue, sophisticated designs of high-frequency magnetic components must be pursued by intensive research [24].…”

Abstract-The objective of this paper is to provide an overview of emerging technologies for modular power converter architectures for electric vehicles. Nowadays, the most common electrical drive-train architecture exhibits one single inverter which is directly tied to the battery. As a consequence, only one high-voltage battery module can be applied and the dc-link voltage of the inverter and its apparent power rating is directly dependent on the available battery voltage. To overcome this restriction, modern power converter architectures with a higher degree of freedom have been proposed. These architectures exhibit modular dc-dc converters to allow different battery technologies to be linked to drive inverters operating independently from each other. To make this development feasible, new components and technologies are evolving which enhance the efficiency over mission cycles while ensuring further integration of the power-converter architectures.Wide-bandgap power semiconductors enable high switching frequencies and miniaturization of passive devices. Smart topology enhancements and control methods allow a significant loss reduction, in particular at light loads, resulting in a higher efficiency of the drive train over the entire driving cycle. Highly integrated bidirectional battery charger systems with intelligent charging strategies inhibit battery degradation and provide opportunities for grid stabilization. It is demonstrated how these technologies are realized and implemented to contribute to the development of future electric vehicles.

“…Compared with a wire or Simulation and measurement of AC resistance for a high power planar inductor design Christian Østergaard * , Claus Kjeldsen * , Morten Nymand * and Rakesh Ramachandran * copper foil winding, the turns of PCB are rotated 90 • . The orientation of the turns influences the inductors ac resistance due to the skin-and proximity effects from the magnetic fields [10]. The ac resistance of PCB winded planar inductor are therefore difficult to determine, when multiple layers, parallel connections and turns are utilized [11].…”
