The advancements in power electronics have led to maximum utilisation of available renewable source of energy. Z-source inverter (ZSI) has been investigated recently into renewable energy applications, because of its single stage operation. ZSI can perform buck-boost operation in single stage, which is not possible with traditional inverter topologies. ZSI provides a unique state in which the upper and lower switches of the same leg of inverter are ON, which is not permissible in traditional VSI. Experimental investigation of grid connected ZSI has been presented in paper. Practical aspects of selection of Z-source (ZS) impedance network parameters are presented.
