Inverter systems that feed electrical power from photovoltaic system into the grid must convert the direct current of the fuel cell into the alternating current of the grid. The DC voltage, which is provided from a sustainable energy source or energy storage device, must be boosted and converted to an AC voltage with a fixed amplitude and frequency. The coupled inductor based single-stage boost three-phase inverter circuit provides boost inversion ability which can eliminate the limitations of conventional voltage source inverter. By regulating the shoot-through zero state and the parameters of coupled inductor, the proposed inverter can boost the bus voltage and desired output voltage even when input DC voltage is low.
