Abstract
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 such systems is proposed. The fundamental frequency component of the flux is confined to the limbs around which the coils are placed, whereas other parts only experiences high frequency flux excitation. As a result, the inductor can be made smaller. The inductor is analyzed and performance is verified by simulation and experimental studies.
