Abstract
A circuit for applying unidirectional pulses to a precipitator, in addition to a base d.c. level supplied by a transformer/rectifier set, includes a rectifier, an inverter and a transformer/rectifier set connected to charge a storage capacitor. Discharge of the capacitor into the precipitator is controlled by a chain of unidirectionally conducting devices (thyristors as shown) which are simultaneously triggered at the desired voltage at the capacitor. In other embodiments breakover diodes are used instead of the thyristors.
