Abstract
Abstract A method of controlling the power used and the ozone generated by an ozone generator. The rate of gas flow through the generator (and/or also the temperature or pressure) is used to either adjust or to limit the output of the power supply. A control signal derived from the gas flow rate is fed to the power supply, influencing its output and thereby affecting the power drawn by the ozone generator. This method enables the concentration or the total quantity of the ozone generated to remain relatively constant with varying gas flow rate, or it can continuously regulate the power level so as to automatically generate the highest possible ozone concentration at any flow rate. In addition, this method allows a single power supply and ozone generator to feed ozone to multiple users with different and/or varying demands, while holding the ozone concentration constant as the users go on and off independently of each other.
