Ac To Dc Converter Circuit Diagram With Transformer. You can also wire your own converter circuit if you want to try converting ac to dc yourself. The first circuit will convert a 220v ac input to any desired output level from 100v to 220v however the output will be a dc so this circuit may be used for operating a foreign equipment which might be employing an ac dc smps input power supply stage.
Primarily the 230v ac power is stepped down to 12v ac 12v rms value of which the peak value is 17v approximately but 5v dc is the required power. D5 zener diode togheter with r1 and c4 provide ic s required 12v voltage. So this stepped down output 17v ac power has to be converted into dc power and then it is to be stepped down to 5v dc.
The transformer is used to step down the 230v ac to 13v ac.
See in the circuit. Size the transformer windings. The transformer is used to step down the 230v ac to 13v ac. Here is a dc voltage regulated transformer power supply circuit.
