How do you build a dc/dc power supply?

How to make a DC power supply using the AC wall voltage!

  1. Step 1: Build a Basic Full-wave Bridge Rectifier. Your circuit should contain:
  2. Step 2: Add a Low-pass Filter. Add a capacitor to your circuit to reduce some variation in the output voltage.
  3. Step 3: Add a Zener Diode.

How do you make a 12V 5A power supply?

I like to use a series of 78xx regulator ICs. Because it is so easy with a few parts. If we want 12V output. So, use 7812….Value on circuit

  1. Vout = 12V—voltage to load.
  2. IT = 5A—total output current to load.
  3. Vin = 20V—input voltage to this circuit.
  4. IbiasIC1 = 12mA —the current to cause IC1 run.

Which transformer is used in DC power supply?

A step-down transformer is used in the first step of AC-DC voltage conversion. It is a device that converts a high primary voltage to a lower value (secondary voltage). A step-down transformer has two coil windings: primary and secondary, with the former having more coil winding turns than the latter.
