  bibo_abstract:
  - 'DC-DC converters for on-board chargers (OBC) of electrical vehicles are usually
    galvanically isolated allowing modular single-phase PFC front-end solutions, but
    require transformers which are more bulky, costly and lossy than inductors of
    non-isolated DC-DCs. Furthermore, for vehicle-to-grid applications, bidirectional
    converters with transformers are generally more complex and have a higher count
    on semiconductor switches than transformerless solutions. However, when using
    non-isolated DC-DC converters within an OBC, the large common-mode (CM) capacitance
    comprising capacitive parasitics of the traction battery as well as explicit Y-capacitors
    connecting the high-voltage DC-system (HV-system) within specific HV-loads to
    ground has to be considered. For the PFC front-end stage, when supplied from the
    three-phase mains this means that generation of high-frequency and high-amplitude
    CM voltages, as it is common e.g. with the conventional six-switch full-bridge
    converter, has to be strictly avoided. For this reason, a modified topology is
    suggested leading to a different mode of operation and to a very low common-mode
    noise behaviour: The three-phase four-wire full-bridge PFC with split DC-link,
    whose midpoint is connected to the mains neutral provides very stable potentials
    at the DC-link rails and therefore it can be classified as Zero-CM-topology.For
    dedicated single-phase operation, as required for most OBC, an additional balancing
    leg may be added to the topology to reduce the required DC-link capacitance and
    allow non-electrolytic capacitors.The function of the bidirectional Zero-CM three-phase
    four-wire full-bridge PFC was verified by simulation and on an 11 kW-laboratory
    sample. The power factor is above 0.999 and an efficiency of 98 % is measured.@eng'
