How do you make a dc power supply circuit?

Step by step method to design 5V DC power supply

  1. Step 1: The selection of regulator IC.
  2. Step 2: The selection of transformer.
  3. Step 3: The selection of diodes for the bridge.
  4. Step 4: The Selection of smoothing capacitor and calculations.
  5. Step 5: Making the power supply safe.

How do you make a 12v power supply?

Constructing Dual Power Supply Circuit:

  1. Step-I: Converting 220v AC into 12v AC using Step Down Transformer.
  2. INPUT: 220V ac, 50 Hz.
  3. OUTPUT: Between outer terminal and middle terminal: 12V ac, 50 Hz.
  4. Step – II: Converting 12v AC into 12v DC using Full Bridge Rectifier.
  5. Here, full bridge rectifier is used.
  6. INPUT: 12V ac.

How do you build a rectifier circuit?

The bridge rectifier is an electronic component that is widely used to provide full wave rectification and it is possibly the most widely used circuit for this application. Using four diodes the bridge rectifier the circuit has a distinctive format with the circuit diagram based on a square with one diode on each leg.

Is a rectifier a power supply?

A Rectifier converts AC (alternating current) to DC (direct current). The rectifier circuit takes alternating current (AC) and converts it into a positive direct current (DC) output. Power supply includes AC power supply and DC power supply.

What is the output of a rectifier circuit?

The output of the full wave rectifier is is, essentially a 12 volt DC supply. There will be a small ripple on this supply, but you won’t really be able to notice it even if you look at the waveform using the oscilloscope.

These are very important circuits in the designing the dc power supply. In our power supply we are using full wave bridge rectifier. This rectifier is made up of 4 pn-junction diodes. The simple diagram of rectifier circuit is shown in figure below

Can we use a 12 volt power supply in a circuit?

We can use a 12V power supply circuit. We may use an unregulated power supply in some circuits that do not require high accuracy. Just have a small ripple voltage, such as a relay drive circuit. If a circuit that requires a constant voltage level should be 12 volts regulator, too.

What is the output voltage of a 2 amp power supply?

To keep the output stable voltage are 5V and 12V at 1A. C3 and C5 are filters, too. And C4 and C6 reduce the frequency disturbs or transient as well. If your load needs more streams. Such as car audio amplifiers It needs a supply voltage of 12V at 2A up. We can easily modify the circuit above.

How to provide DC power supply according to running voltage?

Same condition with other dc equipment that runs on 9 V or 12 V. So we have to provide the power supply according to the running voltage of circuit or equipment. Below is a block diagram of dc power supply in which four steps are given named as: Stepping down voltage :-First step is is scale down the voltage by a step down transformer.
