Abstract
A soft-switching single-ended AC/AC converter suitable for high-frequency electronic lamp ballast is described. In spite of its simplicity, the converter offers excellent performances both on load and supply side, ensuring: high-frequency supply to the lamp; sinusoidal and in-phase supply current; easy control of lamp power; high-efficiency due to the soft switching both at turn-on and turn-off. Steady-state operation, control characteristics and design criteria are discussed, and experimental results reported, showing input and output circuit performance, component stress, and efficiency.<>Keywords
