The work describes AC/DC converter design for communication devices used in advanced metering infrastructure. At the beginning we describe some typical power supply topologies used in electricity metering devices and possible solutions for our design. Further we describe the topology and priciple of operation of Flyback converter that we use in our application. Focus of our work is the design of electronic components where the main focus is the design of Flyback transformer, due to its large impact on the operation of the converter. We present some electromagnetic compatibility and safety standard issues in designing switchmode power supply. At the end we present development of the converter and the results of our work.
