Transformerless PSU, is it worth it?

When it comes to the design of a power supply that needs to convert AC mains voltage into a fixed DC voltage, it is the norm to think that a transformer is required to achieve that design goal. In this article, a different alternative will be presented, and more importantly, it will be simulated and compared to the standard transformer solution in terms of cost, size and performance.
