In this paper, a novel multilevel dc–ac inverter is proposed. The proposed multilevel inverter generates seven-level ac output voltage with the appropriate gate signals’ design. Also, the low-pass filter is used to reduce the total harmonic distortion of the sinusoidal output voltage. The switching losses and the voltage stress of power devices can be reduced in the proposed multilevel inverter. The...
In this paper, a photovoltaic (PV) gird-connected micro-inverter controlled by power factor correction (PFC) controller is implemented. The PFC controller is adopted to control the inverter output current sinusoidally. Besides, the maximum power point tracking control circuit can get the maximum power form PV modules. The duality between the PFC circuit and the inverter circuit is presented first...

In addition, the low pass filter is used to reduce the total harmonic distortion of the sinusoidal output voltage.
