A study on Transformer less full bridge inverter for ozone generator

This paper proposes a Transformer less full bridge invert with resonant inductor operated in phase shifted pulse width modulation for ozone generator to overcome the usage of transformer in the electrical circuit. Ozone cell is modelled with the parallel combination of resistor and capacitors, and Dielectric Barrier Discharge is carried out to produce the ozone. The proposed model is simulated using MATLAB and the power consumption by the cell is validated with different phase angle shifted and tabulated. The proposed model is up to the level of the transformer based model. The advantage of the system is by using the resonant inductor itself can generate the required voltage level to produce the ozone.
