Device for the generation of ozone and a process for its operation

A device for the generation of ozone, comprising:

• a high voltage transformer having a primary winding and a secondary winding;
• a converter for supplying a square wave current of variable amplitude and of variable frequency to said primary winding;
• an ozone generator connected across the secondary winding of said high voltage transformer, including a pair of electrodes separated by a solid dielectric and a gas path;
• and
• variable compensation reactance means connected across a selected of the primary and secondary windings of said transformer for maintaining a resonant frequency of a resonant circuit including the compensation reactance means and the ozone generator at a desired frequency both when the ozone generator is in a start state and in an operating state, including a compensation choke and a switch connected to said choke for switching said choke into or out of said resonant circuit in dependence on the state of the ozone generator;
• wherein the compensation reactance means has an inductance and said converter has a frequency selected so that the resonant frequency of said resonant circuit formed by said compensating reactance means and said ozone generator lies below the operating frequency of said converter in all operating conditions of the converter.
