Abstract :
This paper presents the analysis of a water pumping system from photovoltaic cells using a current-fed parallel resonant push-pull inverter, for residential applications in rural areas. The power structure is particularly simple and robust. It works with ZVS commutation. Its main features are: one power processing stage; simple control strategy; lower harmonic distortion of the load voltage; and natural isolation. The principle of operation, design procedure and experimental results are presented
