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 ...

Circuit designers often encounter the adverse effects of common-mode noise on a design. Once a common-mode problem is identified, there are several ways that it can be resolved. Circuit designers ...

According to IEEE/ANSI Standard C62.41-1991 (formerly IEEE Standard 587), Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits, the worst normal mode surge expected inside a ...

Download this article in PDF format. Important changes in the way electricity is generated and used—such as increasing reliance on energy from renewable sources, the change to efficient variable-speed ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...
