Abstract
An AC/DC converter is provided for connecting to conductors of a multi-phased alternating current generator or network, which is built redundantly for protection against a total loss and which loads the AC generator essentially without non-linear distortion and where several power factor correction circuits, arranged in parallel with one another, are provided. A number of rectifier circuits are included which are independent of each other and equal to the number of phases of the generator. Each rectifier circuit has six rectifier elements which are connected in pairs to terminals of the generator and, by the formation of bridges, are commonly connected to the output conductors of the rectifier circuits. Each rectifier circuit is connected to a one phase power correction circuit. At least one switch is provided for each rectifier circuit. The switch or switches are associated with at least one pair of rectifier elements and are used to always separate associated pairs of rectifier elements from the conductors associated with the generator. Sensors are included for the functional control of the phases of the generator and the one phase power factor circuits. A switch control logic circuit is connected through conductors with the sensors and which, based on the signals from the sensors, closes or opens the switches of the rectifier circuits.
