Abstract :
Summary form only given, as follows. Summary form only given. An ozone production method using a switching power supply is presented. After the source voltage rectified and filtered by bridge diode and capacitor, it is converted to AC voltage with variable frequency by full bridge inverter which switches are IGBT transistors. This signal frequency can be varied between 10 kHz and 30 kHz. This signal magnitude is increased by high voltage ferrite-core transformer, which is isolated by silicone oil and PTFE material. The acquired signal is applied to an ozone generator tube, which is based on the silent discharge method. This tube has two concentric electrodes and it is composed of a discharge gap and dielectric material of glass. Supplying oxygen gas from one side of the tube and applying a high voltage creates silent discharge and corona zone, which converts some of the oxygen into ozone. The behavior of the ozone generator tube are studied using various simulations and practical results of created the plant. Various conditions of production are investigated for achieving an optimal conditions.
