12v Dc Power Supply Circuit Diagram

12v Dc Power Supply Circuit Diagram

A 12v dc power supply is a simple circuit that converts alternating current (AC) from the wall outlet to direct current (DC) that can be used to power electronic devices. The circuit consists of a transformer, a rectifier, and a filter. The transformer steps down the voltage from the wall outlet to a lower voltage that is suitable for the rectifier. The rectifier converts the AC voltage to DC voltage. The filter smooths out the DC voltage so that it is a clean, stable voltage that can be used to power electronic devices. The following diagram shows a simple 12v dc power supply circuit:
