摘要:Parallel three-level T-type inverters (3LT(2)Is) can increase the capacity of the distributed generation system. In this situation, the zero-sequence circulating currents (ZSCCs) will occur in the common dc-link voltage of parallel 3LT(2)Is. This paper presents a novel ZSCC reduction method based on the developing selective harmonic elimination pulse-width modulation (SHEPWM) for parallel 3LT(2)Is. And each inverter is made to operate with a different PWM pattern. Compared to the conventional methods, the proposed method can remove about p times the number of harmonics with the same switching frequency. The performance and effectiveness of the proposed method were confirmed by experimental results.
