Abstract :
In this paper the design and implementation of an electronic ballast for fluorescent lamps using a very low cost microcontroller (μC) is presented. The ballast has been especially developed for lighting applications in railways, where the International Union of Railways (UIC) 555 code must be fulfilled. The μC is used to optimize the lamp ignition and supply, and to regulate lamp power against line voltage, thus fulfilling UIC 555 requirements. Also, protection features such as lamp soft reignition, overcurrent and undervoltage are included using the μC.
