Design and implementation of an electronic ballast for UV-based ozone generation using a low cost microcontroller

In this paper the design and implementation of an electronic ballast for UV lamps using a very low cost microcontroller (/spl mu/C) is presented. The /spl mu/C is used to optimize the lamp ignition and supply, allowing the control and regulation of lamp power. Also, protection features such as overcurrent, undervoltage and overtemperature are included using the /spl mu/C. The electronic ballast can drive lamps up to 40 W which are employed to generate ozone in water disinfection processes.
