The image shows a regulated power supply circuit with multiple voltage outputs. 1. Input Power: The circuit receives 220V AC from the mains supply through a plug. 2. Step-down Transformer: A 24V transformer is used to step down the 220V AC input to a lower AC voltage suitable for rectification. 3. Bridge Rectifier: The AC output from the transformer is fed into a bridge rectifier, which converts AC (alternating current) into DC (direct current). 4. Filtering: A 35V capacitor is connected after the rectifier to smooth the pulsating DC and reduce ripples. 5. Voltage Regulators: Different voltage regulator ICs (from the 78xx series) are used to provide stable DC output voltages: 7805 → 5V output 7809 → 9V output 7812 → 12V output 7815 → 15V output 7818 → 18V output 6. Ground (GND): A common ground line is shared by all the regulators to complete the circuit. 👉 In summary, this circuit converts 220V AC mains power into multiple regulated DC voltages (5V, 9V, 12V, 15V, and 18V)...
