Abstract
Z-source grid-connected inverter for interfacing with photovoltaic cells is developed in this paper. The application of photovoltaic cell normally faces the shading problem of solar light: this will lead to inconsistent power generation and low system efficiency; therefore, the z-source circuit is applied in grid connected inverter application to improve the boosted dc bus voltage capability. The operation of a z-source grid-connected inverter is explained. The 1-kW prototype the z-source grid connected inverter is demonstrated including simulation and experimental results. The simulation and experimental results illustrate that a z-source inverter is a promising technique to apply in a grid-connected inverter in order to improve the overall grid-connected inverter efficiency and solve the shading problems. © 2011 IEEE.
