Inverter circuit using CD4047 IC 150watts inverter
Hello Engineers. Inverters are a necessity in areas with a load shed or powercuts. Also necessary in offices, shops, etc. So that the day to day electricity requirements can’t be interrupted. Today I am going to discuss a 150 watts inverter circuit using CD4047 IC. This is a stable square wave inverter circuit for powering […]
Fixed Voltage Regulators ICs with accurate Datasheets
Hello Engineers, we need to get desired or fixed voltage supply many times in many applications while designing some applications or circuits. For this, we need to use voltage regulators. So in this post, I am going to tell you in detail about the basic types of fixed voltage regulators and their classifications on the […]
Automatic Battery Charger Circuit for 12v Lead-acid
Hello Engineers, Today I am going to discuss an automatic battery charger circuit designed by me.12V lead-acid batteries are being used in today’s world in a large number of applications/devices too. They can be used in inverters, computer UPS, kids automotive rechargeable buggy cars, Automotives(transportation vehicles), engineering projects, etc. Some of those devices have an […]
UPS Power grid for wifi router and broadband 12v 1.5A.
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 […]
