Abstract: A high voltage power supply comprises a three-phase high voltage transformer (3) and a three-phase high voltage bridge rectifier (4). A primary side of the transformer (3) has three input terminals connectable to the phases (A, B, C) of an industrial three-phase mains net, and a secondary side of the transformer (3) has three output terminals connected to three corresponding input terminals of the bridge rectifier (4). The bridge rectifier (4) is configured to supply a rectified high voltage to a load (2). The power supply further comprises a switching device (22) configured to switch between a first state, in which all input terminals of the transformer (3) are connected to corresponding phases of the net for operation in a three-phase mode, and a second state, in which at least one of the input terminals of the transformer (3) is disconnected from the net for operation in a single-phase mode.

Abstract: A high voltage power supply for an electrostatic precipitator comprises a high voltage transformer, a high voltage bridge rectifier and a semiconductor switch controller configured to control an output power level of the high voltage power supply. A control unit (50) is configured to determine a firing angle of firing pulses for the semiconductor switch controller. During normal operation, a peak voltage value is measured and stored in each half period. When a breakdown is detected, a residual voltage (Ur) over the electrostatic precipitator is measured. A firing angle (α1) of a firing pulse to be provided to said semiconductor switch controller in the first half period after the breakdown is determined from the latest stored measured peak voltage value (Ubef) and the measured residual voltage (Ur) based on a predetermined relationship between the firing angle (α1) and said measured voltages.
