Measurement of an ozone generator using a phase-shifted PWM full bridge inverter

This paper proposes the measurement of an ozone generator using a phase-shifted pulse width modulation (PWM) full bridge inverter as a power supply. The method of electrode parameter measurement for an ozone generator is presented. An electrode set is represented by an equivalent circuit by parallel capacitor and resistor. The test was performed with high-frequency high-voltage ac power supply. Then voltage and charge characteristics were obtained leading to calculating values of the parallel capacitor and resistor. The validity of the obtained parameters is verified with a comparison between simulation and experimental results. It has proved that the proposed equivalent circuit with parameters obtained from the proposed method is valid which is in agreement with experimental results. It can be used for power supply and electrode design for generating ozone gas. The correctness of the proposed technique is verified by both simulation and experimental results.
