    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. © 2010 IEEE.

    This paper proposes the high-voltage high-frequency power supply for an ozone generator using a phase-shift pulse width modulation (PWM) full bridge inverter with constant applied electrode voltage. The circuit operation is fully described. The high-frequency transformer and ozone generator mathematical models are also included for preliminarily calculating of instantaneous voltages and currents. The proposed system simulation using the MATLAB/SIMULINK software package is given. In order to ensure that the zero voltage switch (ZVS) is always operated over a certain range of a frequency variation, a series-compensated resonant inductor is included. The advantage of the proposed system is a capability of varying ozone gas production quantity by varying the frequency and phase shift angle of the converter whilst the applied voltage to the electrodes is kept constant. The correctness of the proposed system is verified by both simulation and experimental results. © 2010 IEEE.
