Abstract :
This paper presents a cost-effective electronic lamp driver design for high-intensity discharge (HID) burners based on a stacked buck converter topology. The circuit is operated in zero-voltage switching mode to improve the efficiency, and thereby, enable miniaturization. Among the several possible low-frequency-square-wave topologies, the proposed synchronous stacked buck converter, combined with a boost converter stage operating as power factor corrector, provides a two-stage HID lamp driver with excellent performance.
