All of this is possible because of transformers that will be discussed in this article. To put it simply, a transformer is a device that increases or decreases the voltage. A step-down transformer ...

A step-down transformer is an electrical device that reduces the voltage of an alternating current (AC) power supply. It consists of a primary winding, a secondary winding, and an iron core. When an ...

The ratio between the output voltage and input voltage is the same as the ratio of the number of turns between the two windings. In a step-down transformer, the secondary winding will have fewer turns ...

Abstract: In this article, a soft-switching transformer-less step-down converter based on a resonant current balance module is proposed. An LED driver is taken as an example of the analysis and design ...

Abstract: In this paper, a soft-switching transformer-less step-down convertor based on resonant current balance module is proposed. Here a LED driver is taken as an example to analyze. The converter ...

For this reason, the secondary coil in step-down transformers usually has a larger-gauge wire for the secondary coil than for the primary coil. Since the primary voltage’s current is low ...
