The single-phase and three-phase renewable power generation system for distributed power applications are presented in the paper. The adopted system is consisted of a DC/DC converter with maximum power tracking, a full-bridge converter for isolation and DC voltage regulation and a voltage source inverter for AC power generation. The DC/DC converter is used to draw the maximum power from the renewable energy source. The full-bridge converter with zero voltage switching (ZVS) technique is used to obtain the stable high side DC voltage. The voltage source inverter is used in the output side to generate sinusoidal voltages in the stand-alone power system for the domestic applications, or to output the desired currents in the grid-connected power system for the compensation of harmonic and reactive power due to nonlinear loads. The mathematical analysis of the adopted system was derived and the control scheme was provided. The validity and effectiveness of the adopted system are verified through the experimental results based on the laboratory prototype
