Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however.

A simplified circuit has been proposed for carrying out a practical improvement in the design of the SPD installed on single-phase AC power supply lines. The experimental measurement has verified that ...

Spice is a circuit simulator that you should have in your toolbox. While a simulator can’t tell you everything, it will often give you valuable insight into the way your circuit behaves, befo… ...

If ac power is included internally in your design, grounding or insulation safety methods need to be part of the system in order to function and fail safely.

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s).

When you switch off power to an ac circuit, a voltage spark (or arc) is created inside the switch that’s quickly extinguished—a desirable condition.

ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can ...
