Power transformer

The power transformer is a fundamental machine in the area of ​​power and power. Traditionally they are built to operate at a frequency of 50 Hz and in most of their applications, and more importantly, are the systems of generation, transmission and distribution of energy. Yields are around 98% with high reliability and strength.

Nowadays, power electronics are increasingly present in higher power systems, aimed at transforming and converting electrical energy through the controlled switching of semiconductors. It is in this way that the high frequency transformer (AF) is applied, typically in conjunction with switched sources, converters, solid state transformers, among others.            Boston Gear PM950TF

The importance of a transformer operating at high frequencies is due to the fact that it can be applied compactly and lightly, with reduced losses, guaranteeing the advantages of the traditional transformer. The size of the transformer changes inversely with frequency. The reduction of the core dimension is only possible because the power density increases with frequency, which justifies the incorporation of this equipment in the power electronics systems (AF operation).

In most situations the transformer works only as galvanic isolation, for the protection and safety of equipment and people. Power conversion is done by power electronics.
