Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

Small, isolated power supplies provide power across isolation barriers in applications from electric vehicle traction inverters to factory control modules. In this Power Tip, I’ll examine different ...
