4 Simple Transformerless Power Supply Circuits Explained
Mar 09, 2021As the name defines, a transformerless power supply circuit provides a low DC from the mains high voltage AC, without using any form of transformer or inductor. It works by using a high voltage capacitor to drop the mains AC current to the required lower level which may be suitable for the connected electronic circuit or load.
Internal combustion engine - Wikipedia
An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.
A Designer's Guide to Lithium (Li-ion) Battery Charging
Sep 01, 2016If the charger is left connected to the battery, a periodic ‘top up’ charge is applied to counteract battery self discharge. The top-up charge is typically initiated when the open-circuit voltage of the battery drops to less than 3.9 to 4 V, and terminates
