Tracking method and tracking device for a voltage converter for a photovoltaic system

A tracking device for an inverter for use in a photovoltaic (PV) generation system, for tracking a working point of a PV generator in the PV generation system, comprising:

• first input ports configured to receive an intermediate circuit voltage associated with the inverter;
• and
• second input ports configured to receive an electric power associated with an output power of the PV Generator,
• wherein the tracking device is configured to:
• determine a setpoint value of the intermediate circuit voltage based on the received intermediate circuit voltage and electric power;
• change the intermediate circuit voltage by voltage increments of a predetermined level in a direction towards a lower or a higher voltage based on the determined setpoint;
• and
• limit a mean rate of change of the intermediate circuit voltage in a subperiod between two voltage increments by a maximum mean rate of change, wherein the maximum mean rate of change is determined depending on a level of the intermediate circuit voltage.
