Current-source type parallel inductor-compensated load resonant inverter with PDM control scheme for efficient ozonizer

This paper is concerned with a study on the high-frequency current source-fed type parallel inductor-compensated load-resonant inverter for an ozonizer, together with some output regulation characteristics. In addition, an effective power control method for a current-source inverter type ozonizer is introduced. This inverter can operate under the principle of the PDM (pulse density modulation) and PWM hybrid power regulation strategy. It is noted that this inverter makes the control system simple, thus leading to improve the ozone generation efficiency.
