| Abstract |
In this paper a new high voltage busbar design is presented. This new design consists in inserting
two specialised zones with specific permitivity and permeability. These zones allow to control the
evolution of voltage or current during the switching. The controled parameters are the increasing and
decreasing slopes of current and voltage, voltage and current spikes and oscillations damping. This
control mitigates the electromagnetic emissions. The capacitive zone is made using a high permittivity
ferroelectric dielectric and the inductive zone with a small flat ferrite core. The capacitive zone acts on
electric field and voltages slopes, whereas, the inductive zone acts on current slopes and spikes. The sizes
and the electricals caracteristics are designed to reduce convertor electromagnetic emissions. This new
busbar improves also losses in the IGBT. |
