This work presents a family of integrated electronic ballasts applied to the public lighting system. The electronic ballasts are designed to supply High-Pressure Sodium lamps according to the desired lamp operation characteristics. The viability of use High-Pressure Sodium lamps in the public lighting system of Santa Maria city is studied along this work. Another topic addressed, is the acoustic resonance phenomenon occurrence. It is explained based on a large number of works previously presented in the literature, in order to choose for a reliable method to supply the lamp. The incremental impedance of the High-Pressure Sodium lamp is defined in the frequency domain. This model is used to analyze the lamp and ballast interaction. The presented integrated electronic ballasts to supply High-Pressure sodium lamps take the advantage of low cost and simplicity providing a stable lamp operation.
