Abstract

ZWZW)ZWThe invention relates to a tracking method for a voltage transformer in particular an inverter of a photovoltaic system. In said method an intermediate circuit voltage (U) is repeatedly decreased or increased in one direction to lower or higher voltage by voltage steps of a specified magnitude (?U). The method is characterized in that an average rate of change (|?U/?t|) of the intermediate circuit voltage (U in a partial time period between two voltage steps is limited by a maximum average rate of change the maximum average rate of change being defined according to the magnitude of the intermediate circuit voltage (U). The invention further relates to a tracking device (10) designed to perform the tracking method and to an inverter equipped with said tracking device.
