An Ozone Generator Power Supply for Water Purification

In this paper, a high-voltage resonant power supply for ozone generation is introduced. The proposed circuit includes a power switch, a resonant capacitor, and a step-up transformer. In addition, it operates under the zero current switching (ZCS) condition which results in higher efficiencies. The simulation results show a sinusoidal output pulse with peak value of 8kV and 1.66us pulse width which is generated from 500V DC input voltage. A hardware prototype with 150V DC input and 2.4 kV output pulse has been implemented. The pulse repetition frequency is set to 15 kHz. The simulation and experimental results are presented in order to validate the converter as well as the operation circuit specifications.
