A photovoltaic module inverter is designed and implemented in this thesis. The module inverter structure includes a high step-up DC-DC converter and a full bridge inverter. The module inverter transfers DC voltage into sinusoid voltage wave. The operating principles and the steady-state analysis of continuous conduction modes of the high step-up converter are discussed. The DSP controller TMS320LF2407A is used to achieve the system starting check, abnormal state detection, maximum power point tracking, and islanding detection. Finally, a prototype circuit with input range from 20 V to 40 V and 220 Vrms/200 W output is implemented. The highest efficiency of the overall system is 86.24%.
