When a dry-type transformer fails unexpectedly, production stops without warning. For many industrial and commercial facilities, each hour of downtime translates to significant financial losses, ...

A new type of DC-DC converter based on Hybrid-switching Method™ and a novel Hybrid Transformer™ enables a high step-down voltage conversion and provides a regulated output voltage of 1V from a 48V ...

Whether you’re just getting into electronics or could use a refresher on some component or phenomenon, it’s hard to beat the training films made by the U.S. military. This 1965 overview of ...

A line of standard and custom-designed toroidal step-down control transformers offers an improved alternative to the conventional stacked lamination type. Their efficient core construction makes them ...

As you may know I've recently relocated to Germany and brought most of my stuff with me (accidentally or not) including my cordless DeWalt tools. I gave all of the corded stuff the packers didn't pack ...

What are the peak load voltage and dc load voltage in the figure shown above? The transformer has a turns ratio of 5:1. This means that the rms secondary voltage is one-fifth of the primary voltage: ...

This article is based on the 1999 National Electrical Code (NEC). Installing transformers in accordance with the NEC is critical to ensuring a safe electrical installation as well as a reliable power ...
