[0042] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0043] like figure 1 As shown, the present invention relates to a method for suppressing output harmonics and DC components of a single-phase grid-connected photovoltaic inverter, which is suitable for sequentially connecting a photovoltaic array 100, a boost circuit 200 for DC / DC conversion, and an inverter 300. photovoltaic grid-connected power generation system.
[0044] The suppression method of the present invention utilizes the voltage and current detection device and the digital controller also provided in the photovoltaic grid-connected power generation system. On the basis of the original control algorithm, two compensations for the boost circuit 200 and the inverter 300 are added. Suppression link.
[0045] For the suppression link of the boost circuit 200, its duty cycle needs to be controlled to obtain a stable intermediate voltage.
