Patent ID: 8199542

Claim:
A device for generating a DC voltage or a DC current, comprising: at least one rectifier element including a control input connected to a control unit the rectifier element being controllable by the control unit in such a way that phases of half-waves to be transmitted of identical polarity are partially cut off; and at least one transformer that has at least one primary winding to be connected through leads from a power supply lead to an AC voltage source and at least one secondary winding connected to a load, the windings being disposed on an associated magnet frame that functions to carry a magnetic flux, wherein the primary winding is connected through the at least one rectifier element to the AC voltage source such that for each AC half-wave of corresponding polarity, a primary current can be carried through the rectifier element and through the primary winding, the primary current always driving the magnetic flux through the magnet frame in the same direction thus providing a direct voltage on the secondary winding that is connected to the load without a rectifier element in a connection path between the secondary winding and the load.
