method of powering corona discharge in ozone generators

A method of powering corona discharge in ozone generators having a power supply including a high-voltage transformer, and having a corona discharge cell including a dielectric electrode and a metal electrode, said method comprising the steps of:

• providing said high-voltage transformer with a single-cycle waveform input including discrete bipolar pulses each consisting of a pair of adjacent unipolar pulses of opposite polarity, wherein the first unipolar pulse of each said bipolar pulse has a polarity such that the dielectric electrode is driven initially electronically negative relative to said metal electrode;
• separating each bipolar pulse from the next bipolar pulse by a time interval, with the width of said bipolar pulse and of said time interval providing a bipolar pulse repetition rate having a frequency distribution;
• and
• broadening said frequency distribution.
