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.

Abstract: A method and circuit arrangement for measuring in-phase current and quadrature current in an electrical alternating current power supply is disclosed. The invention uses a microprocessor whereby four integral values A.sub.1 through A.sub.4 are combined in such as to allow determination of the in-phase current and the quadrature current. The invention is useful in recording in-phase and quadrature components of current from an alternating current power supply.
