To cope with power from large-scale renewable systems, more and more power electronic converters are used in parallel. Typically, carrier interleaving is used, thus leading to a decrease in filtering requirements. However, this causes additional circulating current to flow between the modules of the converter. The modules of the parallel converters are Voltage Source Converters (VSC). Usually, a coupled...
The quality of voltage waveform of the parallel connected inverters can be improved by interleaving the carrier signals. However, an additional coupled inductors (CIs) are required to suppress the circulating current between the interleaved VSCs and often connected in a whiffletree configuration. The integration of the line filter inductor and the coupled inductors in a single magnetic component for...
