Abstract :
This paper presents a single power processing stage electronic ballast for HID lamps. A DC-DC buck converter that controls the current and the power of the lamp, a power factor pre-regulator based on discontinuous conduction mode boost converter and the inverter are combined in a dual fed full bridge BIBRED converter. It operates with a low frequency current driving the lamp. All signals of the power stages are provided by a dedicated microcontroller. A 70 W prototype without acoustic resonance and no stroboscope effect was implemented.
