Abstract: PURPOSE:To obtain the electrostatic precipitator of sure performance with a comparatively simple circuit constitution by constituting so as to change the connection of phase of a transformer or the connection of rectifying diodes so that the direct current high pressure output is made in a noncontinuous wave shape. CONSTITUTION:In three phase alternating current power source AC, controllers 1 which are phase controllers such as thyristors reactors 4, and a boosting transformer 6 with V-connection, the absolute value of voltages are equal and the phase difference is 120 deg.. The current is converted into direct current by a rectifying circuit 6, and supplied to an electrostatic precipitator 8 through a reactor 7. By this constitution, the voltage at (a), (a') in the figure is about 1/2 of crest value because the boosting transformer 5 has V-connection, and a direct current high power of noncontinuous wave shape is obtained, and the inverse ionization phenomena generated in this period in the precipitator is reduced and the energy is expected to be saved. Thus, the electrostatic precipitator of sure performance is obtained by the comparatively simple circuit.
