| Abstract: | A new five level inverter is proposed in the paper, which could be applicated in the solar photovoltaic （pv） grid power sys- tem. The main advantage of the inverter is the circuit and control method is simple when producing the same number of output levels. The topology and principle of the main circuit are analyzed in the paper. The modulation of stair-waveform adthmetic based on Minimum Lower-order Harmonic Content is also introduced. Finally, the simulation has been done and it is in accordance with theoretical results. |
