SMPSs have become very common nowadays and we find them being used in the form of AC to DC adapters wherever needed. The best example is our cell phone chargers which are actually compact SMPS 5V chargers. Solar charger devices are also becoming popular nowadays and folks are constantly in ...
MPPT stands for Maximum Power Point Tracking, a charger concept specifically intended and designed for acquiring highly efficient solar power harnessing. Solar panels are excellent devices since they allow us to harness free electrical energy from sun, however the present devices are not very efficient...
The second design explains a cheap yet effective, less than $1 cheap yet effective solar charger circuit, which can be built even by a layman for harnessing efficient solar battery charging. You will need just a solar panel panel, a selector switch and some diodes for getting a reasonably e...

In all the four above power bank cell phone charger circuits, the charging of the two 3.7V cells can be done with the same TIP122 network which is discussed for the first boost charger design. The 5V zener should be changed to a 9V zener diode and the charging input obtained from any ...
The bootstrapping network refers to a small circuit network around the gates of the high-side MOSFETs which enables the high-side MOSFETs to conduct freely by ensuring that its gate voltage is always around 12V higher than its instantaneous source voltage. ...
In this post I have explained a battery charger circuit specifically designed for camper and motorhome applications, so it can serve as an effective
When an exhausted cell is placed, a note around 1 kHz is provided. The device has been examined with battery voltages between 1.5 V and 14 V, utilizing a BC547 as Q1 and an BC557 as Q2. You can also use the battery in the reverse polarity and still make the circuit work withou...
