Abstract
A high-voltage AC-DC converter is provided that converts alternating current into high-voltage direct current to be provided to a load, e.g. for use as an electrostatic precipitator. The converter includes at least one transformer, wherein the transformer includes at least one primary winding on the AC-side and at least two secondary windings on the DC-side. The converter further includes at least one rectifier rectifying alternating input current, comprising at least one transistor bridge converting the resulting direct current into alternating current, the transformer transforming the resulting alternating current, and comprising at least two high-voltage rectifiers connected to each of the secondary windings, wherein the output voltage of the high-voltage rectifiers is connected in series.
