Implementation of pulse-density modulation PDM in an ozone generation system and its contribution to the characteristic efficiency curve. Rev. ing. univ. Medellín [online]. 2014, vol.13, n.25, pp.137-149. ISSN 1692-3324.

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.
