Power Supply – Block Diagram (AC – DC conversion process)

Power Supply block Diagram

Many electronic circuits need a direct current (DC) voltage source, but what we commonly find are voltage sources of alternating current (AC). In order to achieve a direct current voltage source, the alternating current input must follow a conversion process.

Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator Why use a transistorized voltage regulator? If we use a half or a full-wave rectifier we can convert an AC voltage in a DC one. This converted voltage is unregulated, because the output voltage is not constant and can change due to variations of the load value. To reduce these variations we connect […]
