  • It is well known that a zero-sequence circulating current could exist in parallel three-phase converters with common DC bus. However, this conclusion is normally drawn out while the magnetic coupling between phases being neglected. In fact, for the cost and size, the cores of reactors and transformers that used in three-phase inverters are normally three poles. The magnet couple between three poles makes the zero-sequence circulating currents change significantly from that of three-phase… CONTINUE READING
