Abstract

In this paper, the voltage source series compensated inductor type capacitive load-resonant high-frequency inverter with a high-voltage matching transformer link is presented for driving a silent discharge ozone generating tube load used as a newly-developed ozonizer. The optimum design value of the series compensated resonant inductor for the capacitive load of an ozone generating tube is indicated. The effective power regulation scheme of this ozonizer using a voltage-fed resonant inverter is proposed, which is based on a PDM (pulse density modulation) related PWM strategy due to DSP implementation. The effectiveness of this ozonizer is proved in experiment as well as the simulation results.
