Abstract

The invention relates to a high voltage DC power supply system for energizing a number of fields of an electrostatic precipitator (12), said system comprising a high voltage DC-bus (1) consisting of a three-phase transformer- rectifier (3,4) and a L-C filter (5,6) and a number of individual high voltage DC power supplies (8) one for each field of the precipitator (13), and where the high voltage DC-bus (1) is common for these high voltage DC power supplies.
