Design and Implementation of Ozone-Driven System with Enhanced Adaptive Input-Voltage Capability

Abstract

With the swift progress of techniques the concept of high voltage ozone excitation for cleaning and sterilizing is being widely utilized in industrial applications and daily lives Based on this critical importance this dissertation proposes an ozone-driven system with high adaptability of input voltage along with the analysis made on the control strategies feedback mechanism resonant configuration and application methods The dissertation starts with the discussion on the enhancement of ozone-driven circuit along with a high adaptability of input voltage This proposed circuit excels at the extension of input voltage by way of circuit improvement and transformer design Both circuit analysis and hardware implementation validate the method in the achievement of wide input range where the power transfer and soft-switching is confirmed as well Next considering that the ozone load is highly dependent on the charging system yet the performance of charging speed and discharging endurance by the constant voltage and constant current charging mode allows for a further improvement A new charging method is therefore proposed in this dissertation which is verified by the system analysis and experiment in order for the optimization of performance improvement As for the provision of a power source for the charging circuit and the controller of the ozone-driven system this dissertation proposes a controllable dual-output DC converter The dual-output voltage is generated through the integration of energy storage components with control strategies where the completed system is found to be unaffected by connected loads Conclusively with the development of control strategy and system topology made in this dissertation the completed circuit design has exhibited the merits of component integration and expansion of application areas The outcomes gained from this dissertation are served as beneficial references for the research and development of universal and movable ozone-driven systems
