Ni-Cd battery charger circuitThis circuit can be primarily used for charging 12V Ni-Cd battery packs. Any way 6V and 9V battery packs can be also charged
Simple UPSThis is the circuit diagram of a simple UPS that can deliver 12V unregulated and 5V regulated DC. The transformer T1 steps down the mains voltage to 12V AC and then the bridge B1 rectifies it.
UPS - Uninterrupted Power SupplySome time disturbance of power supply creates a number of problems. Especially in sensitive departments such as Radar System
Inverter Project 12v DC to 120V ACAn Inverter is a device that converts 12 volts dc to 120 volts ac, which is what we use in our homes.
Multi-voltage Supply CircuitThe multi-voltage supply circuit shown relies on a multi-winding transformer to generate several AC voltages from a single AC input.
