Summary, etc. <p class="MDPI17abstract">A digital controlled dielectric barrier discharge (DBD) AC power supply is designed and investigated. The power source design with a diode bridge rectifier and PWM inverter along with driver circuit are presented. A step up transformer is designed to carry 4.6kW and 10 kVp-p for a dielectric barrier discharge (DBD) AC power supply and for ozone generation. An STM (STMicroelectronics) microcontroller is employed to control the phase shift angle of the PWM (Pulse Width Modulation) inverter. The operating frequency of the PWM inverter is 25 kHz. Zero voltage detection can be reached and achieves maximum efficiency. In addition, a high voltage transformer is included The practical results shown that the DBD power supply can be controlled at the chosen value and extreme efficiency can be 87.45 % at 4.6 kW/10 kVp-p.</p>
