Control for a photovoltaic module arrangement, photovoltaic module arrangement and inverter for a photovoltaic module arrangement

摘要

Control (120) for a photovoltaic module arrangement (100), comprising: • a control circuit (302) for generating a control signal for controlling at least one switching unit (116, 118) for limiting the current flow in a series connection of photovoltaic modules (102, 104, 106) connected to a DC voltage line (112); • a simulation circuit (316) which simulates at least one switching unit (116, 118); • wherein the simulation circuit (316) is configured to receive a control signal and to provide an output signal in response to the control signal; and • wherein the control circuit (302) is set up to change the control signal in its signal frequency and / or its signal amplitude depending on the output signal.
