Electronic devices

Electronic devices should be powered by direct current supply of DC (direct current) which can be stable for good. The battery or batteries are the source of DC power supply is best. However, for applications that require a larger power supply, the source of the battery is not enough. A major source of power supply is the source of alternating AC (alternating current) from power plants. It required a power supply device that can convert AC current into DC. In this article presented the principles of the power supply circuit (power supply) linear ranging from the simplest rectifier circuit to the power supply was regulation.

Principle rectifier (rectifier) The simplest is shown in Figure-1 below. The transformer is needed to lower the AC voltage from the grid at the primary coil becomes smaller AC voltage in secondary coil.
