Ac To Dc Power Supply Schematic Diagram. Below is the schematic for the dc power supply so that we can see how all the parts are connected and are brought together. Circuit diagram and explanation the schematic for this ac dc converter circuit is simple.
Regulated power supply is an electronic circuit that is designed to provide a constant dc voltage of predetermined value across load terminals irrespective of ac mains fluctuations or load variations. In order to achieve a direct current voltage source the alternating current input must follow a conversion process like the one shown in the power supply block diagram below. Looking over his notes from ac theory the student proceeds to build this power supply circuit complete with a low pass filter at the output.
Above are the parts needed to create a dc power supply.
The transformer is used to step down the 230v ac to 13v ac. Below is the schematic for the dc power supply so that we can see how all the parts are connected and are brought together. D5 zener diode togheter with r1 and c4 provide ic s required 12v voltage. A student learns that a rectifier circuit is often followed by a low pass filter circuit in an ac dc power supply to reduce ripple voltage on the output.
