摘要： A power control method for tracking a Maximum Power Point (MPP) in a photovoltaic system including a solar cell and a boost converter. The power control method includes finding the MPP by applying a continuous ON/OFF signal to the boost converter as a first control signal for controlling a duty ratio of the boost converter, and maintaining an operating point of the photovoltaic system at the MPP by applying a second control signal for controlling the duty ratio to the boost converter depending on a constant-voltage command. In tracking an MPP in a photovoltaic system, an MPPT algorithm may remain at the MPP, without self oscillation, improving fast dynamic characteristics upon a change in solar radiation.
