LM317 is an adjustable voltage regulator IC. In this project, we will be making a 1.25V to 37V LM317 adjustable voltage regulator circuit. This IC can provide an output current up to 1Amp. It’s a three-terminal positive voltage regulator IC. This voltage regulator requires only two external resistors to set the supply voltage. It has […]
The circuit in this article shows you a simple way to build a 12v to 230v inverter circuit diagram of 100watt power using 555 IC. 555 is a timer ic which is used to generate time delay. On these properties, it can be used to make a power inverter. CD4047 Inverter circuit This Inverter does […]
This Automatic battery charger circuit cuts-off power supply when the battery gets fully charged. This circuit can charge any battery like Li-Po, Lead Acid, or Ni-Cd if you set it properly. Everyone needs a Battery Charger with a Battery. It charges the Lead Acid Battery up to 50Ah. You can set the battery cutoff threshold by setting […]
In this project, we will make CD4047 Inverter, and also we will discuss why they are not a good solution. An inverter is a device that converts DC voltage to AC. They are very important for power backup in a remote location like villages where there is a frequent power cut off problem also in […]
Mostly we need a 5-volt power supply for micro-controllers, digital chips, op-amps, etc. So, we want a small as well as reliable 5v power supply. The article is completely about such a type of power supply. We are using LM-7805 IC to build a 5-volt power supply. 7805 is a 5V fixed three-terminal voltage regulator. […]
