The invention relates to a process for operating an inverter with n servo components (2, 4, 6) operated in parallel and consisting of m converter valves (tln, ...,Tmn), in which these n servo components (2, 4, 6) are powered on the input side by a common d.c. source (UZ) and are interconnected on the output side via a transformer (10) with a downstream filter-capacitor circuit to execute the process. According to the invention, each of the m generated control signals (UATl, ..., UATm) is taken together to n parallel-operated converter valves (Tl1, Tl2, ..., Tln or ... or Tm1, Tm2, ..., Tmn) of the n servo components (2, 4, 6), a release signal (UFSl or ... or UFSm) is generated at the exact time when each of the n parallel-operated converter valves (Tl1, Tl2, ..., Tln or ... or Tm1, Tm2, ..., Tmn) generates an output signal (Uoff11, Uoff12, ..., Uoffln or ... or ... Uoffm1, Uoffm2, ..., Uoffmn) and each generated release signal (UFSl or ... or UFSm) releases a control signal (UATl or ... or UATm) for n parallel-operated complementarily switching converter valves (Tl1, Tl2, ..., Tln or ... or Tm1, Tm2, ..., Tmn). An inverter is thus provided with only one regulating and control device (8) for n servo components (2, 4, 6), whereby the load current is distributed symmetrically over the n servo components (2, 4, 6). |
