Abstract :
Repetitive control is installed into the current control of the residential photovoltaic power generation system. The generation system is interconnected to the utility grid. The control command and disturbance of the inverter is a periodic line frequency value. The control stability and suppression of the disturbance are realized by the repetitive control of the current signal. The control is implemented into a single-chip microcomputer by the software. 18 kHz control of the current realizes low distortion output and enables us to use smaller power inductor of the filter
