230v ac to 12v dc and 5v dc Regulated Power Converter

230v ac to 12v 1A dc and 5v 1A dc power supply circuit diagram

In many electronics projects we see that there is requirement of fixed voltage power supply , fixed means no any fluctuation in voltage . output of any circuit is fully depends on input voltage supply and it should be constant. Any sensitive circuit is more essential to operate on regulated power than any normal circuit. If i use RF operation in any circuit then its frequency must be constant because there is a small bit of voltage and current fluctuation make more variation of output signal. We use voltage regulator to regulate the voltage supply which maintain constant supply.220/230v ac to 12v/5v DC Regulated Power DC converter Bridge Rectifier.

Ac power is easily available at anyone mostly , DC source is not easily available and if available there is not more time availability of continuity and at a time it is necessarry to Recharge. AC to DC makes the great stability of power supply and not required to Charge again. So it is more usable and more availablity of voltage and current than battery . 

• Converting from AC to DC is not easy way . AC has different charecteristic with respect to DC, and more risky to human and any living thing.

1. The first stage is in AC to DC is to make down the voltage as required level using step down transformer

2. Second stage is the Rectifing the signal , Rectifiers are used to rectifying the signal. Rectifying means convert the ac signal to dc as possible.

3. Third stage is Filter the signal . After rectifyng the signal it consists ripple noise in dc signal that is not perfectly suitable for operate the circuit. Capacitor is used to filter the signal.

4. Fourth stage is the Regulation, Regulation make the more stable of any signal to give the circuit to constant supply. Regulator ic or Zener diode is used to make the constant signal.

Capacitor 1500uf 25v-1, 0.1uf-2
LM7805 ic-1,for 5v and 7812 for 12v

You need 9v dc then use 7809 and 7805 for 5v .

minimum 15 v input power is required for regulation of 12v using 7812

      I want 12v 4amps dc supply.so can i use 12v 4amps transformer in the place of 12v 1amp transformer

      Hello Mr.Aman, may I know what is the purpose of putting in 2 units of 0.1uf (104) capacitors before and after L7812. How does it play its role in the final circuit diagram in this article ? Thank you in advance.

        This is used to maintain the stability at the output and suppress the high frequency ripple noise. By shunting the AC Ripple signal to ground, provide reduced AC at output DC. it does improve transient response
        But this capacitor is Not strictly required.
