Abstract
A regulating installation for the power output conveyed to a three-phase user; including switches transmissive in both current directions having triggering characteristics, with the switches being positioned in two of the three power supply phases; first and second impulse generators; and an element transmitting a control signal to the impulse generators dependent upon the difference in the actual value and a reference value of the power output being regulated. Each of the impulse generators has, respectively, one switch associated therewith, the generators each being synchronized by a power supply phase and transmitting a triggering impulse to its associated switch. The first impulse generator is synchronized through a T-phase uninterruptedly applied to the user, and the second impulse generator is synchronized through an R-phase connected thereto by the switch associated therewith.
