Patent ID: 7012825

Claim:
A converter for providing at least one DC output from at least one AC supply with at least one phase and at least one DC supply, the at least one AC supply supplying an AC signal comprising positive and negative half-periods, the converter comprises at least one coil that is in connection with the at least one DC output, the converter contains controllable contact means for connecting and disconnecting the at least one AC supply and the at least one DC supply to/from said converter wherein connecting and disconnecting of the AC and DC supplies to/from said converter is based on phase information of the AC signal, whereby the AC signal fed to the coil is divided into periods, wherein the periods of the AC signal alternatingly originate from either positive or negative half-periods of the AC signal and current pulses from the at least one DC supply; and wherein the current pulses from the at least one DC supply are regulated in dependence of the AC signal; and wherein the converter contains means for voltage regulating the at least one DC output.
