A filter unit for a static converter, notably an inverter, comprises at least one module having four capacitors arranged on a support with a square base in two groups connected in parallel to the power supply terminals of opposite polarities, each group comprising two series-mounted capacitors. The voltage at the mid-points of the two groups is fixed by a voltage divider comprising two balancing resistors, and an auxiliary impedance formed by the intermediate part of the connecting device. The support base is provided with coupling means to enable modular assembly by associating several modules identical on the four sides of the base.
