power electronics

Most of our electronics projects are powered by a Lead Acid battery, in this project let us discuss how to recharge this lead acid Battery with a help of a simple circuit that can be easily understood and built from home. This project will save yourself from investing in a battery charger and help you to extend your battery life. So let's get started!!!!

Batteries are generally used to power up the Electronic Circuit and Projects, as they are easily available and can be connected easily. But they drained off quickly and then we need new batteries, also these batteries cannot provide high current to drive a powerful motor. So to solve these problems, today we are designing our own Variable Power Supply which will provide…

In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features.

Some digital electronic modules, like accelerometers, work on a voltage of 3.3V, and some work on 2.2V. Some even work on lower voltages. With this, we cannot get…

Voltage Multipliers are the circuits where we get very high DC voltage from the Low AC voltage supply, a voltage multiplier circuit generates voltage in multiple of peak input voltage of AC, like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output, in case of Voltage Tripler circuit. Multimeter only reads the RMS (root mean voltage) value…

If you got fed up of buying new batteries for your circuits and want a reliable power source, then here is way. We use our Laptop or PC to charge you cellphones, similarly we can use power supply from our Computer’s USB for our circuits. Computer’s USB is a good power source for 5v DC regulated supply. Also when there is a circuit which consist motor like DC motor, Servo etc…
