This is a take-off on Mr. Marian’s “Simple Micro Ampere Meter Circuit” that utilizes active circuitry and an analog meter to make sensitive DC current measurements. A reader subsequently asked if it ...

This AC to DC converter circuit is capable of converting an alternative voltage within 70V – 260V range into a DC voltage within 180V to 350V DC range, so it can be used for 110V and 220V too. To ...

Here's an alternative to rewinding AC coils for operation on DC circuits. It's relatively simple - all it takes are a few calculations and a little bench testing. Want to skip the time and expense of ...

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.

Conclusion It is essential to know the significant difference between an AC and DC isolator switch. Is a DC or AC circuit being created? Is an inductive or resistive switch to be used?

EC motors are DC brushless motors that are controlled by external electronic circuit board. This provides greater control and higher efficiency. The Basics of DC and AC Motors DC motors rely on ...
