Abstract- This paper describes the use of three-phase high voltage transformer-rectifier sets (HV TR sets) in low resistivity applications, as an alternative to high frequency switch mode power supplies (HFPS). The operation of threephase HV power supplies will be described showing the most important waveforms and equations for their design and sizing. Then the information that should be included in the rating plate for performing theoretical calculations will be reviewed. Afterwards the results obtained in a practical application will be presented.
Keywords- Electrostatic precipitators, HV power supplies, three-phase TR sets
