Efficient ozone generator using full-bridge inverter and its performance evaluations

Ozone utilizing technologies and its applications are spreading very rapidly. This paper presents a switched mode power supply designed for such type of load. The voltage source that is a full bridge inverter developed for driving a silent discharge type high frequency ozone generation tube. Developed inverter type ozone generator system has high performance, such as power and frequency tuning, industrializes production and so on. The state-of-the art ozone generator using a voltage fed type high frequency inverter is investigated and its operating principle is considered for driving ozone-generating tube. The full bridge inverter uses MOSFET transistor switches that its frequency can be varied between 3 kHz and 30 kHz, and high voltage ferrite-core transformer, which is isolated by silicone oil and PTFE material, increases its magnitude. The power consumption and power factor of the ozone generation tube are measured on the low voltage side of the transformer that includes the transformer loss. The measured parameters can be used to achieve to the optimal production point, in the constant feed flow oxygen, cell length and cell pressure along with ozone production quantity. Developed scheme has proved high performance for ozone generation system by experiment and it is under implementation.
