Abstract :
This work presents a single stage converter to drive high intensity discharge metal halide (HID - MH) lamps. The integration of two DCM boost converters, in an interleaved way, with a half bridge voltage inverter and the use of a square current waveform applied to the lamp results in an electronic ballast with high power factor and reduced power spectrum spread to avoid the lamp´s acoustic resonance. To stabilize the lamps power a low bandwidth feedback control loop was designed and implemented.
