| Abstract |
In PV grid connected power conditioners, usually
both boosting the PV array voltage, and bucking the dc bus
voltage for injection of a sinusoidal current to the grid is
required. In this paper the design procedure of Z-source
converter as a single phase PV grid connected transformer-less
inverter is presented. The converter has one switch less than the
conventional two stage power conditioner, which leads to
reduction of cost. An optimum modulation pattern for the
switches is proposed. The design of the converter is verified by
simulation. |
