Abstract

 The ozone generation systems generally use the pulse amplitude modula­tion (PAM) to vary or control the ozone concentration. The results obtained after the implementation of pulse density modulation (PDM) in the power supply system of an ozone generation and the improvement achieved in the efficiency curve is presented in this paper. PAM and PDM techniques were applied in ozone generation system with push-pull inverter resonant self. The adjusted voltage amplitude of the PDM waveform power is de­termined from the condition of the PAM waveform where the maximum efficiency was obtained; Thus achieving increased efficiency in 60% of operating points ozone generation system.
