Abstract：Euler Lagrange(EL) power model of photovoltaic grid-connected inverter is set up. On the basis of EL power model and passivity based control theory, passivity based power controller is designed utilizing desired maximum output power of photovoltaic grid-connected inverter calculated MPPT of photovoltaic array and damping injecting. Maximum power of photovoltaic array MPPT is good tracked by output power of grid connected inverter based on passivity based power controller, and maximum power transfer is realized. Unity power factor and low current harmonic distortion in AC side are obtained. Simulation and experimental results show that maximum power transfer of photovoltaic grid connected inverters can be realized by passivity based power controller based on EL power model.
