The source voltage sees a light load and produces an output voltage that can supply more current than the original source. Same for a current mirror.

In this Design Idea, we explore several ways to use SPICE [1-3] circuit analysis software to determine the Thevenin and Norton equivalent circuit parameters of linear active networks. The Thevenin ...

This circuit produces a regulated current in a load, the range of which is determined by the tap chosen. The current value within that range is set by a control voltage.

In Part 2, we’ll do the same for low-voltage circuit breakers and fuses. It’s important to note that this discussion is intended only to illustrate (by way of example) the ANSI methodologies to find ...

Despite their designed current-handling capacity, such circuits still need current limiters and circuit breakers to protect them from fault conditions.

Voltage regulators are also a common option, especially with existing circuits where additional commercial or industrial load is being added. However, distribution voltage regulators are relatively ...
