Abstract (en)
[origin: US4670829A] An electrostatic precipitator is fed high voltage pulses by a pulse generating circuit including a high voltage transformer and a first thyristor switch connected in series with a primary winding of the transformer. Magnetic saturation of the core of the high voltage transformer is prevented by recurrently short circuiting the primary winding of the transformer by means of a second thyristor switch connected in parallel to the primary winding. The second thyristor switch is closed for a period of time extending from a first instant following a high voltage pulse crest to a second instant at or before the start of a pulse generating cycle subsequent to the pulse crest.

Bei der Versorgung eines Elektroabscheiders (A) mit Hochspannungsimpulsen wird eine magnetische Sättigung des Hochspannungstransformators (H) verhindert, indem nach jedem Impuls die Primärwicklung (W1) zur Unterstützung des Entladevorgangs des Elektroabscheiders (A) durch einen Halbleiterschalter (T2) kurzgeschlossen wird.
