Abstract

Interharmonics have become one of the challenging issues in photovoltaic (PV) systems. One of the reasons for interharmonic emissions is the maximum power point tracking (MPPT) control. In cascaded H-bridge (CHB) PV inverters, due to the potential superposition of the MPPT perturbations of individual PV cells, a higher oscillation may appear in the equivalent total DC voltage, leading to large interharmonics in the grid. To mitigate the interharmonics from CHB PV inverters, a series interharmonic filter is proposed in this paper, which employs a series H-bridge cell as an active filter. With the proposed control, the equivalent DC voltage can be maintained oscillation-free, thereby suppressing the interharmonics. In practice, the interharmonic filter can be either an additional unit, or a redundant cell in the cascaded PV converter. Simulations and experimental results have validated the effectiveness of the proposed solution.
