Abstract :
A high voltage source generating the fast rising square wave voltage has been developed for a high efficiency ozone generator. The voltage source incorporated a rotating spark gap switch. Lifetime of the voltage source is determined by erosion of the spark gap switch. In order to obtain a long life time, various electrode materials have been experimentally tested. Sintered tungsten with thorium dioxide has the smallest erosion rate among the materials tested in the experiment. Using this material as the switch, the high voltage source was constructed to operate an ozone generator with an ozone generating rate of 20 g/h.<>
