In the literature, several AC/DC converters are studied and presented. All kinds of topologies and techniques are covered under this topic. This includes single-switch, half-bridge and full bridge topologies as well as hard, quasi-resonant and resonant switching. Different techniques are also developed to control these converters ensuring high power factor. The aim of this paper is to present a low-cost solution for low-power applications. A high-frequency AC to DC converter that respects the EN 61000-3-2 standard and is suitable for applications in the power range of 300 W, is presented. Its topology is based on a full-bridge series-resonant converter that operates below half the resonant frequency. The converter features zero-current for both turn-on and turn-off and reduces the switching current for the output rectifier. These advantages make the series-resonant topology suitable for operation at high frequency. Thus, electromagnetic integration of the LCT network (inductor-capacitor-transformer) is successfully applied owing to the fact that the inductor and the capacitor values are relatively small at this range of frequency. Computer simulation and experimental results are presented.
