FAQS 4
What are circulating current reduction methods for modular inverters?
The reduction methods for modular inverters are compared in terms of eficiency, performance, and reliability. The possible approaches for circulating current reduction are categorized into three groups–hardware, control, and modulation. Each reduction method is discussed according to the category.
Why do modular inverters have a closed circuit?
Modular inverters have a closed circuit when each inverter shares the common DC source and AC bus. The cir-culating current is generated by diferences in each inverter, such as hardware parameters and control process. The circulating current deteriorates the output current quality and degrades the reliability of the parallel system [12–15].
How circulating current flows between inverters?
The circulating current flows between the inverters when the reference voltages difer according to the dead time, imperfect symmetry in hardware, and dependent control of parallel inverters. Diferent zero-sequence voltages Vzsv1 and Vzsv2 are injected into each module based on the discrepancy of the reference voltages from Eq. (10).
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.
