Abstract
The paper deals with some peculiar aspects of the design of interleaved voltage source converter (IVSC) topology in high-power applications such as renewable energy systems and electric vehicles. The IVSC offers advantages like power sharing among multiple modules, improved power quality, redundancy, and fault tolerance. The design of an IVSC mainly involves the selection of the number of deployed converters and the choice of suitable semiconductor devices with the aim to reach a desired overall efficiency for an assigned operating condition. The paper develops an approach to characterize through a straightforward procedure the dependence of the IVSC' power losses on the number of the interlaced converters, on the employed semiconductor devices used and on a properly conceived set of key parameters which define the system operating conditions. The proposed methodology allows to…
