CD4047 50Hz /60Hz 100W Inverter Circuit

Image
The CD4047 CMOS-based two-MOSFET inverter circuit board is a square wave inverter that oscillating the input DC voltage at 50-60Hz frequency using an external transformer to produce a 220V AC output. This mini inverter can be handy for camping and outdoor emergency work where electricity is unavailable to charge your device batteries with a charger or power AC light bulbs. Here, we will discuss and explain the workings of this simple DC-AC power converter along with its circuit diagram .

Universal Single 3.7V Battery Charger Circuit

Image
The Chinese universal single 3.7V battery charger is designed to safely and efficiently charge rechargeable Li-Ion (18650, 16340, 14500), AA, and AAA batteries with a voltage rating of 3.7V. It charges them to their nominal voltage of 4.2V while providing a steady current of 400mA. The charger incorporates a Bi-color LED that indicates the charging status, with the LED emitting a red light during the charging process and automatically switching to green when the battery is fully charged. Here, we will discuss and explain the workings of this 3V3 battery charger along with its circuit diagram .
