Abstract :
In this paper a simple single-stage AC/DC converter, based on the flyback topology, is presented. With a single switch, a fast-regulated output voltage is achieved and although the line current is not sinusoidal, the converter complies with the standard IEC 1000-3-2 for low frequency harmonics in the medium power range. The major advantages of this converter are its size and the efficiency. Design guidelines, analysis of the line current and extensions to other topologies are analyzed. Experimental results are included in the paper
