Abstract: The method for calculating the pulse firing pattern for a transformer of an electrostatic precipitator, the method comprising a) defining a target parameter indicative of the power to be supplied to collecting electrodes and discharge electrodes of the electrostatic precipitator, b) calculating a first parameter indicative of the power supplied to the collecting electrodes and discharge electrodes using the pulse firing pattern being calculated, in case one additional pulse is fired, c) calculating a second parameter indicative of the power supplied to the collecting electrodes and discharge electrodes using the pulse firing pattern being calculated, in case two additional successive pulses are not fired, d) selecting at least one pattern element on the basis of the first parameter or second parameter, e) repeating steps b), c), d), e).

Abstract: The pulse firing pattern (20) for a transformer (16) of an electrostatic precipitator (9) comprises first elements indicative of a pulse to be fired and second elements indicative of a pulse to not be fired. The pulse firing pattern further comprises couples of adjacent second elements and at least two first elements.
