Abstract
This paper proposes a new single-phase seven-level grid-connected inverter. Operational principle with switching function are analyzed. A digital proportional-integral current-control algorithm was implemented in a TMS320F28335 DSP to keep the current injected into the grid sinusoidal. To verify the performance of the proposed inverter, PSIM simulation and experimental results are also shown in this paper.
