Our technical reviewer pointed out that C ac should be an X-rated safety type, and I think we'd both feel better if the ground symbol wasn't there! SMPS circuits offer an efficient way to reduce AC ...

This, of course, isn’t true. Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1.

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. Here are the basics of watts and ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create ...
