Converter module for converting electrical power and inverter for a photovoltaic system having at least two converter modules

The invention relates to a converter module (10) for converting electrical power by means of a converter circuit (12), which converter circuit has at least one power-electronics semiconductor switch (14) controlled in a clocked manner. The converter module (10) comprises a housing, a first intermediate circuit connection (18a), and a capacitor (20) for stabilizing a direct voltage present at the first intermediate circuit connection (18a), which capacitor is arranged in the housing (16) and is connected to the first intermediate circuit connection (18a) and to the converter circuit (12). The converter module (10) has a second intermediate circuit connection (18b), which is connected to the capacitor (20) and to the first intermediate circuit connection (18a), wherein the first and the second intermediate circuit connection (18a, 18b) are designed for connecting to intermediate circuit connections (18a, 18b) of further converter modules (10) for converting electrical power.
