4 FAQs about Inverter parallel DC component

How circulating current is generated in a parallel inverter?

The circulating current is generated when the parallel invert-ers operate with an interleaving scheme to improve the qual-ity of the output current. The isolated transformers to the ac sides can mitigate the circulating current by eliminating the closed current path.

How does circulating current affect the power rating of a parallel inverter?

The circulating current deteriorates the output current quality and degrades the reliability of the parallel system [12–15]. Harmonic components of circulating current can influence the inverter life cycle, limiting the power rating of the total parallel-connected inverter [16, 17].

What is the output voltage of a parallel inverter?

In the practical system, the output voltage of two inverters which are connected in parallel either be same in magnitude U and angular frequency w or be different voltage amplitude U and U + Δ U and angular frequency w a and w b . The inverter output voltage differs by a phase angle ∅. The circulating current i ab shown in Eq.

How does a parallel inverter work?

The dc sides of the inverters are connected to the common dc source, and the ac side of each inverter is directly connected to the common ac bus through two filter inductors. Since there is no bulky isolation transformer, the power density of parallel system can be improved.
