What is a Non-contact AC voltage detector? It is an AC voltage detector, that can be used to test live wires without any connection, hence the name. Therefore, it is safer than the neon screwdriver ...

Single-phase to single-phase AC/AC Power Converter laboratory prototype hardware design and drive. A new generalized step-down single-stage line-frequency switching AC/AC power converter topology is ...

I have built this circuit on a zero PCB for testing it and my board after soldering all the components is looked like as shown in the image below. As you can see, the project looks simple and easy, so ...

In this DIY project article, we will build a simple, cost-effective, powerful LED driver circuit that could be useful to power up an entire 12V light string that has more than 100 or even 200 LEDs. As ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

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 ...

This air-conditioner (AC) power saver circuit can control the operation of two separate AC units, reducing energy consumption during preset periods and cutting overall load and electricity bills.

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and a frequency range from 20 Hz to more than 2 MHz.
