DC POWER SUPPLY BLOCK DIAGRAM PDF
Power Supply block Diagram (AC - DC conversion process
Oct 01, 2019Power 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 like the one shown in the power supply block diagram below.

4-2 Figure 4-1A.— Block diagram of a basic power supply. As illustrated in view B of figure 4-1, the first section is the TRANSFORMER. The transformer steps up or steps down the input line voltage and isolates the power supply from the power line. The RECTIFIER section converts the alternating current input signal to a pulsating direct current. However, as you proceed in this chapter you[PDF]

by what is in effect a DC to DC converter, to produce a regulated DC output at the required level. Hence a SMPS can be used to convert AC to DC, such as in a desktop computer power supply, or DC to DC, either step up or step down in many different battery powered systems. Fig. 3.0.1 shows a block diagram example of a[PDF]

Load − The load which uses the pure dc output from the regulated output. Block Diagram of a Power Supply Unit. The block diagram of a Regulated Power supply unit is as shown below. From the diagram above, it is evident that the transformer is present at the initial stage. Though we had already gone through the concept regarding transformers
Dc power supplies-Introduction - CircuitsToday
From the block diagram, the basic power supply is constituted by four elements viz a transformer, a rectifier, a filter, and a regulator put together. The output of the dc power supply is used to provide a constant dc voltage across the load. Let us briefly outline the function of each of the elements of the dc power supply.
