The invention relates to a process for operating an inverter arrangement with n parallel servo components (2, 4, 6) in each case consisting of m converter valves (Tln, ..., Tnn), these n servo components (2, 4, 6) being supplied from a common direct-voltage source (Uz) at the input end and being combined with one another at the output end by means of a txansformer (10) followed by a filter capacitor circuit (12), and to a circuit arrangement for carrying out the process. According to the invention, each of the m drive signals (UAT1,...,UATm) generated is jointly supplied to n parallel converter valves (Tl1, Tl2, ..., Tlu and ... and Tm1, Tm2, ..., Tmn, respectively) of the n servo components (2, 4, 6) and an enable signal (UFS1 and ..., and UFSm respectively) is generated in each case precisely when each of the n parallel converter valves (Tl1, Tl2, ..., Tln and ... and Tml/ Tm2,... Tmn, respectively) generates an off signal (Uoff11, Uoff12, ... Uoff1n and ... and UOffm1, UOffm2, ..., Uoffnm, respectively) and each enable signal (UFS1 and ... and UFSm, respectively) enables a drive signal (UAT1 and ... and UATm, respectively) for n parallel converter valves (Tl1, Tl2, ..., Tln and ... and Tm1, Tm2,..., Tmu, respectively), switching in complementary fashion. This provides an inverter arrangement having only one regulating and control device (8) for n servo components (2, 4, 6), the load current being distributed symmetrically to the n servo components (2, 4, 6).
