Compact, Ferrite Core Transformerless Inverter Circuit

The circuit diagram of a compact transformeress inverter using ferrite core inductor is shown in the following article, the image was provided to me by one of the avid readers of this blog Mr. Ritesh. The design is a full fledged configuration with includes most of the features such as ferrite transformer winding details, low voltage indicator stage, output voltage regulation facility etc.




I would appreciate if anybody could help identify the various stages, and explain them in details.

  2. hi sir you done a great job ,i want to build one so i need your help the IC im very confuse is it a CD 556 LM556? and if it would be possible for you to send the PCB of it i will be appreciate,thank you looking forward to hear from soon

    1. Thanks Daniel,

      Any 556 IC will do, the initial prefix does not matter.
      I do not have the PCB design for this circuit, so would be unable to provide it to you

  3. Hi. Why is the rectifyer at the output? is this not an inverter? is this a DC-DC converter?
    Why not a filter instead of the rectifyer?
    Thanks.

    1. the rectified high voltage is again switched back into AC mains at the output for the appliances. see the extreme right hand side section.

  4. Transformerless? It has a ferrite core trafo... this is a transformer.

    1. when inverters are discussed, transformers by default refers to heavy bulky iron cored transformers, which is not present here, the small ferrite trafo can be considered as good as an electronic component.
