Adapter / power supply is a DC voltage source used to provide the voltage or power to various electronic circuits that require a DC voltage to operate. Basic circuit of the power supply is none other than a rectifier which is a circuit that converts the signal back and forth (AC) becomes Direct Current (DC). The resources obtained from the battery, solar cell, generator AC / DC.
Various resources will be discussed, one type of power supply that goes through a process of changing from an AC voltage (alternating) to DC (Direct Current).
Conversion process starts from Rectification by diodes, wrinkle-smoothing voltage (Voltage Ripple Filter) using the setting (regulation) by the regulator circuit.
Settings include the conversion of voltage or current levels. On the technical regulations on the manufacture of power supply, we know the techniques of linear power regulation and switching regulation technique.
