Purpose
These transformers are the basic part of high frequency power converters. Like standard 50 Hz transformers, they transfer the electrical power from the primary to the secondary side, by changing voltage and current levels and keeping the galvanic isolaTCon of the load from the mains, according to the safety standards related to the different applicaTCon fields. Usually the mains voltage is recTCfied by a full-wave diode bridge and a capacitor, the DC link feeds the transformer through an electronic switch (or more than one, depending on the topology) controlled in the range of some tens or some hundreds of kHz.
Features
Depending on the applicaTCon, the rated power, the working voltage, the rated current, the environment condiTCons, the designer has to choose the best topology for the power converter. The most used ones are flyback, forward, push-pull converters for power levels up to 1 kW, while for higher values half-bridge or full-bridge converters are the more suitable topologies. Sirio develops and produces small size switch mode transformers, up to 1 kW, and switch mode power transformers, up to 20 kW and more.
Industrial applicaTCons typically requires specific features in terms of electrical data, efficiency requirements, safety standards, robustness, mechanical dimensions, and so on, so it is rarely possible to consider standard power supplies, or standard transformers.
That heterogeneous reality made Sirio decide to dedicate great efforts to the switching transformers development, in order to be able to supply special components, opTCmized for the automaTCc producTCon: this kind of approach makes possible the creaTCon of products saTCsfying the customer specificaTCon and enhanced by the Sirio technology.
