Abstract


In recent years, the ozone technology has been widely applied in the field of sewage treatment, medicine, food, chemical production, air purification, drinking water disinfection, etc., and show a very good development prospects. However, China's current industrial ozone generator vast majority of workers frequency high voltage, low efficiency, high energy consumption, and the open-loop control, have prevented the extension of the ozone technology applications. Compared to the ozone generator and the power frequency, high frequency ozone generator with a compact, high ozone concentrations and low power consumption advantages, is the development direction of the ozone generator. Especially for high-power the ozone generator IF ozone generator system and its supporting power has become a focus for researchers. Therefore, for this hot, power inverter IF the dielectric barrier ozone generator system. The main work of this study include the following four aspects: 1. The dielectric barrier ozone generator load characteristics. Commonly used in high-power industrial the dielectric barrier ozone generator as the research object, starting from the physical mechanism and characteristics of dielectric barrier discharge, assumed that the load applied voltage sine wave and square wave, the ozone generator load characteristics The theoretical analysis of the results of these analyzes provide important theoretical basis for the design and development of the follow-up of high-efficiency ozone generator power inverter; 2. the dielectric barrier ozone generator power circuit topology study. Comparative analysis of the two commonly used dielectric barrier ozone generator power load resonant inverter topology, select the series resonant inverter circuit as a high power dielectric barrier type ozone generator power inverter topology; 3. Dielectric barrier type ozone generator power control mode. A comparative analysis of the ozone generator power output power control mode select a phased power adjustment and frequency tracking capacitive phase shift in a phased power regulation, the chopper power adjustment, FM power adjustment and phase shift PWM power adjustment control PWM dimming function as ozone generator power output power control mode control and Matlab / Simulink simulation; 4. ozone generator power inverter design and experiment. This article presents the main power circuit, control circuit and drive circuit design process, and open-loop power control experimental study to verify the correctness and feasibility of the power supply design.
