Tips: Working principle of rectifier transformer

The windings are composed of two independent wires of primary and secondary and share an iron core. The primary winding is connected to the AC power supply, and the alternating current flows in to generate magnetic potential. The magnetic flux flows in the closed iron core. Alternating current of the same frequency is induced in the secondary winding.

At the beginning of the transformer, the turns ratio of the secondary winding is equal to the voltage ratio. In order to obtain multiple output voltages, some transformers can have multiple secondary windings and taps.

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
