| Abstract | ||||
| This paper presents a practical designing of dielectric barrier discharge DBD ozone generator. The parametric determination of DBD ozone reactor or chamber is of significant importance because the power supply design is based on these parameters. The power supply is divided into two stages: one of them is responsible for generating a variable pulse signal (pulse width modulation PWM). This modulated signal (control signal) will be adjusted to possess the first harmonic of its Fourier series that equals the resonant frequency of ozone chamber. This harmonic is that corresponding to the resonance operating frequency of DBD ozone reactor parameter values. The second stage is concerned with inverting of the DC voltage to AC high voltage. Owing to the control signal hasn’t the capability of directly driving the ozone chamber, the control signal will be connected to MOSFET gate. As a result of this connection, the applied DC to the primary side of high voltage high frequency (HVHF) transformer will be converted to puled signal with pulse voltage equal to that of the applied DC voltage value. Our scope in this work is to design and practically verify the microcontroller module of Pulse width modulation (PWM) generator and MOSFET with HVHF transformer inverting circuit. In addition, practical electrical waveforms of DBD ozone generator modules will be demonstrated. MicroC compiler, Proteus and Cadance_ORCAD_ Allegro PSpice software will be used in this work. | ||||
