PFC converters are widely used in industrial drive systems. The modulation scheme and the topology of the converter have a considerable impact not only on the switching losses, but also on the volume of the passive components, i.e. the EMI filter (CM and DM) and the dC link capacitors. In order to evaluate this impact, different modulation schemes for 2L and 3L topologies are analysed in this paper based on comprehensive converter optimizations. In these optimizations also a model for the EMI filter is included and the optimal converter volume including the EMI filter is evaluated for the different topologies and modulation schemes. Thus, significant differences in the converter volume can be observed for the different modulation schemes. Also the impact of SiC semiconductors on the system performance is analysed. The 3L-NPB modulation scheme with a NPC topology offers the best compromise of heat sink, EMI filter and DC link capacitor volume., 2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), ISBN:978-90-75815-27-6, ISBN:978-90-75815-26-9, ISBN:978-1-5386-0530-1

Packages of power semiconductors have considerable influence regarding the thermal impedance, the parasitic inductance, which affects the switching losses, and the reliability. In this paper, the performance of a phase leg of a PFC rectifier with PCB embedded power semiconductors is investigated. The mechanical stress in the PCB is analyzed by a FEM simulation and PCB design guidelines are given. The thermal impedance, parasitic inductance and switching losses of a real test setup are measured and compared with commercial modules. Based on this data, an optimization of a PFC rectifier with respect to volume, including the EMI filter, is performed for a converter using PCB embedded power semiconductors and compared to a converter using power semiconductors with conventional packaging. The converter using PCB embedded power semiconductors achieves a 21% lower volume compared to a converter using power semiconductors with conventional packaging., 2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), ISBN:978-9-0758-1524-5, ISBN:978-1-5090-1410-1
