587 – Application
of Pulse Power for Gas Cleaning Direct-Coupled Pulse Energization in
ESP and Pulse
– Design of a Low Cost Pulsed Power Supply for Electrostatic
Precipitators Using Magnetic Switching Technique
The pulse width of commercial pulsed power sets and the repetition rate are limited by the turn-off time of the used power thyristors. The thyristors are loaded with a pulse current of very high derivative and an amplitude many times higher than the average value.
In order to overcome these problems a novel pulsed power supply was developed and designed. It includes a magnetic switch in addition to modern high voltage solid-state
switching technology. The new power supply allows rise times of 2-3 µs and total pulse widths below 10 µs, a repetition rate of more than 400 Hz and a pulse amplitude of more than 100 kV superimposed on a DC voltage. the design is based on an energy saving concept recovering the energy not being utilized in the ESP. First operating tests with a capacitive load are presented and discussed.
Low first costs, a small number of high voltage components and short pulse widths with the potential to further enhancement of the ESP performance at high resistivity dust favor the new concept.
