Abstract :
In this paper two single single-stage AC/DC converters, based on both flyback and forward topologies are presented. With a single switch, a fast-regulated output voltage is achieved. The major advantages of these converters are the simplicity, the efficiency and the clamped voltage on the storage capacitor. Although the line current is not sinusoidal, the converters can be designed to accomplish the Standard IEC 1000-3-2 about low frequency harmonics for a medium power range. Design trade-offs, analysis of the line current and experimental results are included in the paper
