Hello Engineers, A non-stop internet connection is a necessity for all. Although in developed cities, a power cut is very uncommon. But still, it takes place and if your wifi and landline connection isn’t connected to the inverter, then your internet connection and landline may not get power and it is interrupted and all the […]
Voltage multiplier circuits are electronic circuits that multiply the input voltage 2 to 3 or 4 times, and the output voltage RMS is also 2 to 4 times higher. This kind of circuitry basically employs just some diodes and capacitors. It takes AC input and then converts that to higher Amplitude DC voltage. The voltage […]
Hi guys, Today I’m going to discuss a new circuit by me, which is a regulated 220v AC to 5v DC Regulated transformerless power supply using LM7805 and TIP41.The circuit discussed in this article is a bit more than just a few capacitors, diodes, and Zener diodes. So, let’s get started with the materials, then […]
Hello People, Sometimes our batteries in go-carts, inverters, kids buggy toys, emergency lights, etc after a long period of inactivity resist to full charge. They may also stop charging completely or their supply quality degrades to a greater extent. This is due to battery sulfation. In this article, we will discuss more about the battery […]
Hi guys, this a fast charger for charging rechargeable batteries( Fast Battery/cell Charger Circuit)like Ni-Mh or Ni-Cd,(Don’t have an auto cutoff, but after cells got charged the led is consuming all power so there is no chance of overcharge), etc. This charger is also useful to charge 9v rechargeable batteries up to 2500mah. The charger […]
