摘要： A method of finding a power maximum of a photovoltaic generator using an MPP regulator of a photovoltaic current converter by means of which a maximum generator power is set at an operating point of the generator's characteristic curve is intended to supply improved efficiency when the generator is partially shadowed. This is achieved by switching the MPP regulator off in order to next load and/or unload the generator to allow a new operating point of the generator's characteristic curve to set and by next switching the MPP regulator on again.

摘要： A method of matching the power of a photovoltaic system producing electric energy by which a working point at which the system produces maximum power is set by changing the working point in an MPP matching process and by comparing the system power, which changes as a result thereof, is intended to be suited both for stationary characteristic curves and for non stationary generator characteristic curves and to be easy to carry out so that the best working point is always set, even when the system is subjected to external interfering factors. This is achieved in that one or several additional control steps or control cycles are performed in order to track during the matching process a power point changing under external impact for a working point of even higher power to be set.
