ExtremeCircuits presents a small electronic switch that connects a battery to the equipment for a certain amount of time when a push-button is momentarily pressed. And we have also taken the ambient ...
This automatic NiCd charger for 9V NiCd batteries is using 555 timer properties and is very easy to build. Why is an automatic 9 volts NiCd battery charger? Because you can leave the battery for ...
GEORGE TOWN, Grand Cayman, Aug. 28, 2020 (GLOBE NEWSWIRE) -- O 2 Micro ® International Limited (NASDAQ Global Select Market: OIIM), a global leader in the design, development and marketing of ...
In this circuit, a MOSFET protects a reverse-connected battery from excessive current. The MOSFET conducts only when the battery is correctly connected, which lets the battery charge or discharge. In ...

Abstract: This paper describes the design and development of a cellular near-field power harvesting circuit. Its potential to independently power sensor systems without batteries is demonstrated and ...
Abstract: This paper proposes the pre-charge, discharge, and mini-UPS circuits of an auxiliary power network architecture for 10kV SiC-based power electronics building block. The design and working ...
Download this article in PDF format. Proper wiring and probing/contacting are critical to making successful measurements. When testing cells or batteries, using good engineering practices is important ...
We use circuit symbols to draw diagrams of electrical circuits, with straight lines to show the wires. The diagram shows some common circuit symbols. Make sure you know the difference between these ...
This is probably fairly straightforward for an EE to weigh in on so I thought I’d post this question here for posterity in the hopes that it’ll solve the issue for other designers. The challenge is ...
For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
