Analysis of the Harmonic Performance of Power Converters and Electrical Drives

Power converters have progressively become the most efficient and attractive solution in
recent decades in many industrial sectors, ranging from electric mobility, aerospace
applications to attain better electric aircra���� concepts, vast renewable energy resource
integration in the transmission and distribution grid, the design of smart and efficient
energy management systems, the usage of energy storage systems, and the achievement
of smart grid paradigm development, among others.
In order to achieve efficient solutions in this wide energy scenario, over the past few
decades, considerable attention has been paid by the academia and industry in order to
develop new methods to achieve power systems with maximum harmonic
performance aiming for two main targets. On the one hand, the high-performance
harmonic performance of power systems would lead to improvements in their power
density, size and weight. This becomes critical in applications such as aerospace or
electric mobility, where the power converters are on-board systems. On the other hand,
current standards are becoming more and more strict in order to reduce the EMI and EMC
noise, as well as meeting minimum power quality requirements (i.e., grid code standards
for grid-tied power systems).
