With the advent of Electric Vehicles and Internet of things the need for sophisticated power electronic design has increased. These new fields are constantly evolving the demands for high-power motor drives, energy efficient power supplies, wireless power transfer etc.
In this section we will design and test various power electronic projects for a wide variety of applications including EV, Solar, IoT, SMPS Power supplies, LED Drivers, Portable power supplies etc. The section also covers the latest power electronic news and articles to update the readers with latest technology trends.
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…
Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage, using 555 timer…
Small Loudspeaker is a fun project to do, you can connect it to your Cellphone or Laptop through a 3.5mm audio jack and can enjoy your own loudspeaker. You can also connect it to any device which has a 3.5 mm audio output, like TV, music player, video games etc. We have used LM386 IC to amplify sound, with a few external components.

Simple Mic audio amplifier can amplify sound that is given from Microphone. This circuit can be used as “Small mic and loudspeaker system” for a small space like a room. This circuit can also be used in many applications like portable music players, intercoms, radio amplifiers, TV sound systems, Ultrasonic drivers etc. It can also be used as sound sensor for…
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…
Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.
You can also build 6V DC, 9V, 12V,…
You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after some time. A number of technologies are available to make such kinds of systems, like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this Arduino based automatic door…
