Abstract
A power supply converter unit is disclosed, in particular for an electrostatic precipitator, converting the frequency of alternating input supply () to high frequency alternating output (Ua, Ub) by rectifying the alternating input supply () in a rectifier () to a direct current (Udc), which is converted to alternating-current in a full bridge inverter () in a H-bridge circuit with switches () controlled by a control unit (). According to the invention on the input side of the rectifier () and/or in the direct current (Udc) section there is provided at least one overvoltage protection circuitry (-). Furthermore the invention discloses a method of operation of such a power supply converter unit as well as uses of such a power supply converter unit.
