good afternoon sir!!

thank you for this site,sir i have a problem regarding on my 12v, 12 ampere converter,charger power supply..when i used this on my ham radio it drops off..can i used the 7812 ic for this situation? i’d like to turn this to regulated poer supply.does your circuit can fit to my problem?

Thanks for this informative post Mr.genius..
I want to design a similar circuit for my project. As you said in your post that it supplies 12V and 1A output as DC.. And i want about 100mA DC output for my design. So is it possible yo connect some resistor in series and scale down the current? Or i should use some other trick??
your guidance will be much appreciated..
If any one else has good idea plz contact me at sunil.rockon@yahoo.in..
Thanx

Thank for all the good projects you have about inverters.My question is that,can i use step down transformer to make an inverter,if it can, how can it be used.
Can the o/p of a step down transformer be used as the input and the usual input be used as the output.
please help me.

hi..
am a beginner in circuit design
i just wanted to knw on what basis did u select the values of the capacitors…?

i wann design a powersupply which outputs 12v 200ma and without using a transformer this s my first task given to me ….

can u plz help…??

I am trying to get a regulated 12VDC/300 mA output from a supply that varies from 18 to 27VDC. What is the input voltage tolerance of a 7812 regulator? Will it handle 27 volts? If so, your regulator circuit could be just the ticket. Thanks.

hi,
gud day i just want to ask f this type of circuit and parts can also be use in constructing a 12V 12A power supply coz i like ur circuit diagram it so ezy 2 do…i will wait for reply sir ty
