Abstract

The present invention relates to a method for generating from an alternating voltage (1), preferably of mains frequency, a variable d.c. voltage (3) which is applied to the electrodes of an electrostatic precipitator with a voltage level exceeding 30 kV. The alternating voltage (1) is converted (3) to a d.c. voltage, optionally subsequent to transforming-up the d.c. voltage, and the d.c. voltage (via switches ''A'' and ''B'') is supplied pulsewise to the primary winding (23) of a transformer (22), and the output voltage of the secondary winding (28a, 28b) of the transformer is rectified (33, 35, 34) and constitutes the variable d.c. voltage. The pulsated supply of the d.c. voltage to the primary winding of the transformer (via the switches ''A'' and ''B'') is effected at a frequency of between 20kHz and 200kHz.
