Patent ID: 6841137

Claim:
An apparatus for generating ozone and linearly controlling the concentration of the ozone being generated, comprising: means for providing oxygen; means for generating ozone by applying electrical discharge to the oxygen provided by the means for providing oxygen; means for generating a control signal; means for providing a first pulse signal, for the electrical discharge, wherein the first pulse signal providing means is configured to generate a low-frequency pulse having an ON/OFF time ratio depending on the control signal and a high-frequency pulse optimized for the electrical discharge, to mix the low-frequency pulse and the high-frequency pulse, and to generate the first pulse signal having an adjusted ON/OFF time ratio; and means for transforming the first pulse signal from the first pulse signal providing means into a predetermined signal level having a frequency in a range of 1 to 50 kHz, wherein the transformation means is electrically connected to the ozone generation means and the first pulse providing means.
