    • A method for determining a maximum power point (MPP) of a photovoltaic generator (PV) by variation of at least one parameter of search voltage and search current, within a maximally searchable search area on a power/voltage curve is disclosed. The method includes initializing by defining a start point with a start voltage and a start current, searching for the maximum power point (MPP) in at least one search direction by repeated variation of the search voltage or search current in the search area taking account of at least two limiting conditions for limiting the search area, wherein at least one of the limiting conditions for limiting the search area are is determined with evaluation of parameters provided in an operating state already attained during the search, and ending the search if one of the at least two limiting conditions for limiting the search area is met.
    • 公开了一种通过在功率/电压曲线上的最大可搜索的搜索区域中的至少一个搜索电压和搜索电流参数的变化来确定光伏发电机(PV)的最大功率点(MPP)的方法。 该方法包括通过定义具有起始电压和起始电流的起始点来初始化,在考虑到搜索区域中的搜索电压或搜索电流的重复变化的情况下,在至少一个搜索方向上搜索最大功率点(MPP) 用于限制搜索区域的至少两个限制条件,其中用于限制搜索区域的限制条件中的至少一个是通过在搜索期间已经获得的操作状态中提供的参数的评估来确定的,并且如果其中一个 限制搜索区域的至少两个限制条件得到满足。
