ABSTRACT OF THE DISCLOSURE A converter arrangement secure against breakdown, having electronic power circuitry using controlled valves and electronic information-processing control circuitry. The electronic power circuitry is provided only once, but the electronic information-processing circuitry is redundant and contains at least two complete control units. One unit leads and controls the electronic power circuit and at least one other unit operates in parallel, in standby condition. A monitoring device is associated with the control units and, in the event of a disturbance in the leading control unit, switches control of the electronic power circuit to an undisturbed control unit. The arrangement is especially suitable for use in protected converter arrangements which provide interruption-free supply of a load, having the advantage that the expensive electronic power circuitry is provided only once and is not operated in partial- load operation.
