Abstract
This paper proposes the analysis and modelling of an ozone generator using a phase-shift pulse width modulation (PWM) full bridge inverter as a power supply. 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 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 of the converter whilst the applied voltage to the electrodes is kept constant. The correctness of the proposed technique is verified by both simulation and experimental results. © 2008 IEEE.
