Circuit arrangement for at least in sections in the simulation of a magnetic flux by inductances of a dc / dc converter with a plurality of phases

摘要

The present invention relates to a circuit to simulate, at least in sections, of a magnetic flux by inductances (l1, l2,...) of a dc / dc converter with a number of phases, wherein the inductance (l1, l2,...) are magnetically coupled with a first a - and / or output (u (netz1)) for connection to a first network and with a second a - and / or output (u (netz2)) for connection to a second network, wherein the first network a first voltage and the second network has a second voltage, the circuit arrangement circuits, wherein a respective circuit is associated with a phase and the circuits in each case– first means (1) for generating a first signal (k1 _ int, k2 _ int,...), an average current through the of the circuit simulates associated phase, wherein the first means (1) in each case first elements (11) for generating the first signal (k1 _ int, k2 _ int,...), and– second means (2) for generating signals, the at least in sections, the magnetic flux through an inductance (l1, l2,...) to simulate,whereinthe second means (2) of all or some circuits 1, 2, sumje a controller (22), said controller (22) in such a manner with the remaining parts of the second means (2), in that the average currents through the phases of the dc / dc converter with a plurality of phases are the same.
